[0028] The disclosure provides another optical image capturing
system, in order from an object side to an image side, including a
first, second, third, fourth, fifth, six lens elements and an image
plane. The first lens element has refractive power. The second lens
element has refractive power. The third lens element has refractive

elements has at least one inflection point on at least one surface
thereof. At least one lens element among the first through third

of any one of the six lens elements to a coordinate point of
vertical height with a distance of a half of the entrance pupil
diameter from the optical axis on the surface along an outline of
the surface is denoted as ARE. The following relations are
satisfied: 1.0.ltoreq.f/HEP.ltoreq.10.0, 0 deg<HAF.ltoreq.150
deg and 0.9.ltoreq.2 (ARE/HEP).ltoreq.1.5.
[0029] The disclosure provides another optical image capturing
system, in order from an object side to an image side, including a
first, second, third, fourth, fifth, sixth lens elements and an
image plane. Wherein, the optical image capturing system consists
of the six lens elements with refractive power. The first lens
element has positive refractive power. The second lens element has
refractive power. The third lens element has refractive power. The
fourth lens element has refractive power. The fifth lens element
has refractive power. The sixth lens element has refractive power.
At least one lens elements among the second through the sixth lens
elements has positive refractive power. At least two lens elements
among the first through the sixth lens elements respectively have
at least one inflection point on at least one surface thereof.
Focal lengths of the first through sixth lens elements are f1, f2,
f3, f4, f5 and f6 respectively. A focal length of the optical image
capturing system is f. An entrance pupil diameter of the optical
image capturing system is HEP. A distance on an optical axis from
an object-side surface of the first lens element to the image plane
is HOS. A distance on the optical axis from the object-side surface
of the first lens element to the image-side surface of the sixth
lens element is InTL A half of a maximum view angle of the optical
image capturing system is HAF. A length of outline curve from an
axial point on any surface of any one of the six lens elements to a

the entrance pupil diameter from the optical axis on the surface
along an outline of the surface is denoted as ARE. The following
relations are satisfied: 1.0.ltoreq.f/HEP.ltoreq.3.5, 0
deg<HAF.ltoreq.150 deg and 0.9.ltoreq.2
(ARE/HEP).ltoreq.1.5.
[0030] The length of the outline curve of any surface of a signal
lens element in the maximum effective half diameter position
affects the functions of the surface aberration correction and the
optical path difference in each view field. The longer outline
curve may lead to a better function of aberration correction, but
the difficulty of the production may become inevitable. Hence, the
length of the outline curve of the maximum effective half diameter
position of any surface of a signal lens element (ARS) has to be
controlled, and especially, the ratio relations (ARS/TP) between
the length of the outline curve of the maximum effective half
diameter position of the surface (ARS) and the thickness of the
lens element to which the surface belongs on the optical axis (TP)
has to be controlled. For example, the length of the outline curve
of the maximum effective half diameter position of the object-side
surface of the first lens element is denoted as ARS11, and the
thickness of the first lens element on the optical axis is TP1, and
the ratio between both of them is ARS11/TP1. The length of the
outline curve of the maximum effective half diameter position of
the image-side surface of the first lens element is denoted as
ARS12, and the ratio between ARS12 and TP1 is ARS12/TP1. The length
of the outline curve of the maximum effective half diameter
position of the object-side surface of the second lens element is
denoted as ARS21, and the thickness of the second lens element on
the optical axis is TP2, and the ratio between both of them is
ARS21/TP2. The length of the outline curve of the maximum effective
half diameter position of the image-side surface of the second lens
element is denoted as ARS22, and the ratio between ARS22 and TP2 is
ARS22/TP2. The ratio relations between the lengths of the outline
curve of the maximum effective half diameter position of any
surface of the other lens elements and the thicknesses of the lens
elements to which the surfaces belong on the optical axis (TP) are
denoted in the similar way.
[0031] The length of outline curve of half of an entrance pupil
diameter of any surface of a single lens element especially affects
the functions of the surface aberration correction and the optical
path difference in each shared view field. The longer outline curve
may lead to a better function of aberration correction, but the
difficulty of the production may become inevitable. Hence, the
length of outline curve of half of an entrance pupil diameter of
any surface of a single lens element has to be controlled, and
especially, the ratio relationship between the length of outline
curve of half of an entrance pupil diameter of any surface of a
single lens element and the thickness on the optical axis has to be
controlled. For example, the length of outline curve of the half of
the entrance pupil diameter of the object-side surface of the first
lens element is denoted as ARE11, and the thickness of the first
lens element on the optical axis is TP1, and the ratio thereof is
ARE11/TP1. The length of outline curve of the half of the entrance
pupil diameter of the image-side surface of the first lens element
is denoted as ARE12, and the thickness of the first lens element on
the optical axis is TP1, and the ratio thereof is ARE12/TP1. The
length of outline curve of the half of the entrance pupil diameter
of the object-side surface of the first lens element is denoted as
ARE21, and the thickness of the second lens element on the optical
axis is TP2, and the ratio thereof is ARE21/TP2. The length of
outline curve of the half of the entrance pupil diameter of the
image-side surface of the second lens element is denoted as ARE22,
and the thickness of the second lens element on the optical axis is
TP2, and the ratio thereof is ARE22/TP2. The ratio relationship of
the remaining lens elements of the optical image capturing system
can be referred as mentioned above.
[0032] The height of optical system (HOS) may be reduced to achieve
the minimization of the optical image capturing system when the
absolute value of f1 is larger than f6 (|f1|>f6).
[0033] When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| are satisfied with
above relations, at least one of the second through fifth lens
elements may have weak positive refractive power or weak negative
refractive power. The weak refractive power indicates that an
absolute value of the focal length of a specific lens element is
greater than 10. When at least one of the second through fifth lens
elements has the weak positive refractive power, the positive
refractive power of the first lens element can be shared, such that
the unnecessary aberration will not appear too early. On the
contrary, when at least one of the second through fifth lens
elements has the weak negative refractive power, the aberration of
the optical image capturing system can be corrected and fine
tuned.
[0034] The sixth lens element may have negative refractive power
and a concave image-side surface. Hereby, the back focal length is
reduced for keeping the miniaturization, to miniaturize the lens
element effectively. In addition, at least one of the object-side
surface and the image-side surface of the sixth lens element may
have at least one inflection point, such that the angle of incident
with incoming light from an off-axis view field can be suppressed
effectively and the aberration in the off-axis view field can be
corrected further.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0063] Reference will now be made in detail to the exemplary
embodiments of the present disclosure, examples of which are
illustrated in the accompanying drawings. Therefore, it is to be
understood that the foregoing is illustrative of exemplary
embodiments and is not to be construed as limited to the specific
embodiments disclosed, and that modifications to the disclosed
exemplary embodiments, as well as other exemplary embodiments, are
intended to be included within the scope of the appended claims.
These embodiments are provided so that this disclosure will be
thorough and complete, and will fully convey the inventive concept
to those skilled in the art. The relative proportions and ratios of
elements in the drawings may be exaggerated or diminished in size
for the sake of clarity and convenience in the drawings, and such
arbitrary proportions are only illustrative and not limiting in any
way. The same reference numbers are used in the drawings and the
description to refer to the same or like parts.
[0064] It will be understood that, although the terms `first`,
`second`, `third`, etc., may be used herein to describe various
elements, these elements should not be limited by these terms. The
terms are used only for the purpose of distinguishing one component
from another component. Thus, a first element discussed below could
be termed a second element without departing from the teachings of
embodiments. As used herein, the term "or" includes any and all
combinations of one or more of the associated listed items.
[0065] An optical image capturing system, in order from an object
side to an image side, includes a first, second, third, fourth,
fifth and sixth lens elements with refractive power and an image
plane. The optical image capturing system may further include an
image sensing device which is disposed on an image plane.
[0066] The optical image capturing system may use three sets of
wavelengths which are 486.1 nm, 587.5 nm and 656.2 nm,
respectively, wherein 587.5 nm is served as the primary reference
wavelength and a reference wavelength for retrieving technical
features. The optical image capturing system may also use five sets
of wavelengths which are 470 nm, 510 nm, 555 nm, 610 nm and 650 nm,
respectively, wherein 555 nm is served as the primary reference
wavelength and a reference wavelength for retrieving technical
features.
[0067] A ratio of the focal length f of the optical image capturing
system to a focal length fp of each of lens elements with positive
refractive power is PPR. A ratio of the focal length f of the
optical image capturing system to a focal length fn of each of lens
elements with negative refractive power is NPR. A sum of the PPR of
all lens elements with positive refractive power is .SIGMA.PPR. A
sum of the NPR of all lens elements with negative refractive powers
is .SIGMA.NPR. It is beneficial to control the total refractive
power and the total length of the optical image capturing system
when following conditions are satisfied:
0.5.ltoreq..SIGMA.PPR/|.SIGMA.NPR|.ltoreq.15. Preferably, the
following relation may be satisfied:
1.ltoreq..SIGMA.PPR/|.SIGMA.NPR|.ltoreq.3.0.
[0068] The optical image capturing system may further include an
image sensing device which is disposed on an image plane. Half of a
diagonal of an effective detection field of the image sensing
device (imaging height or the maximum image height of the optical
image capturing system) is HOI. A distance on the optical axis from
the object-side surface of the first lens element to the image
plane is HOS. The following relations are satisfied:
HOS/HOI.ltoreq.10 and 0.5.ltoreq.HOS/f.ltoreq.10. Preferably, the
following relations may be satisfied: 1.ltoreq.HOS/HOI.ltoreq.5 and
1.ltoreq.HOS/f.ltoreq.7. Hereby, the miniaturization of the optical
image capturing system can be maintained effectively, so as to be
carried by lightweight portable electronic devices.
[0069] In addition, in the optical image capturing system of the
disclosure, according to different requirements, at least one
aperture stop may be arranged for reducing stray light and
improving the imaging quality.
[0070] In the optical image capturing system of the disclosure, the
aperture stop may be a front or middle aperture. The front aperture
is the aperture stop between a photographed object and the first
lens element. The middle aperture is the aperture stop between the
first lens element and the image plane. If the aperture stop is the
front aperture, a longer distance between the exit pupil and the
image plane of the optical image capturing system can be formed,
such that more optical elements can be disposed in the optical
image capturing system and the efficiency of receiving images of
the image sensing device can be raised. If the aperture stop is the
middle aperture, the view angle of the optical image capturing
system can be expended, such that the optical image capturing
system has the same advantage that is owned by wide angle cameras.
A distance from the aperture stop to the image plane is InS. The
following relation is satisfied: 0.2.ltoreq.InS/HOS.ltoreq.1.1.
Hereby, the miniaturization of the optical image capturing system
can be maintained while the feature of the wild-angle lens element
can be achieved.
[0071] In the optical image capturing system of the disclosure, a
distance from the object-side surface of the first lens element to
the image-side surface of the sixth lens element is InTL. A total
central thickness of all lens elements with refractive power on the
optical axis is .SIGMA.TP. The following relation is satisfied:
0.1.ltoreq..SIGMA.TP/InTL.ltoreq.0.9. Hereby, contrast ratio for
the image formation in the optical image capturing system and
defect-free rate for manufacturing the lens element can be given
consideration simultaneously, and a proper back focal length is
provided to dispose other optical components in the optical image
capturing system.
[0072] A curvature radius of the object-side surface of the first
lens element is R1. A curvature radius of the image-side surface of
the first lens element is R2. The following relation is satisfied:
0.001.ltoreq.|R1/R2|.ltoreq.20. Hereby, the first lens element may
have proper strength of the positive refractive power, so as to
avoid the longitudinal spherical aberration to increase too fast.
Preferably, the following relation may be satisfied:
0.01.ltoreq.|R1/R2|<10.
[0073] A curvature radius of the object-side surface of the sixth
lens element is R11. A curvature radius of the image-side surface
of the sixth lens element is R12. The following relation is
satisfied: -7<(R11-R12)/(R11+R12)<50. Hereby, the astigmatism
generated by the optical image capturing system can be corrected
beneficially.
[0074] A distance between the first lens element and the second
lens element on the optical axis is IN12. The following relation is
satisfied: IN12/f.ltoreq.3.0. Hereby, the chromatic aberration of
the lens elements can be improved, such that the performance can be
increased.
[0075] A distance between the fifth lens element and the sixth lens
element on the optical axis is IN56. The following relation is

[0088] In one embodiment of the optical image capturing system of
the present disclosure, the chromatic aberration of the optical
image capturing system can be corrected by alternatively arranging
the lens elements with large Abbe number and small Abbe number.
[0089] The above Aspheric formula is:
z=ch.sup.2/[1+[1-(k+1)c.sup.2h.sup.2].sup.0.5]+A4h.sup.4+A6h.sup.6+A8h.s-
up.8+A10h.sup.10+A12h.sup.12+A14h.sup.14+A16h.sup.16+A18h.sup.18+A20h.sup.-
20+ . . . (1),
where z is a position value of the position along the optical axis
and at the height h which reference to the surface apex; k is the
conic coefficient, c is the reciprocal of curvature radius, and A4,
A6, A8, A10, A12, A14, A16, A18, and A20 are high order aspheric
coefficients.
[0090] The optical image capturing system provided by the
disclosure, the lens elements may be made of glass or plastic
material. If plastic material is adopted to produce the lens
elements, the cost of manufacturing will be lowered effectively. If
lens elements are made of glass, the heat effect can be controlled
and the designed space arranged for the refractive power of the
optical image capturing system can be increased. Besides, the
object-side surface and the image-side surface of the first through
sixth lens elements may be aspheric, so as to obtain more control
variables. Comparing with the usage of traditional lens element
made by glass, the number of lens elements used can be reduced and
the aberration can be eliminated. Thus, the total height of the
optical image capturing system can be reduced effectively.
[0091] In addition, in the optical image capturing system provided
by the disclosure, if the lens element has a convex surface, the
surface of the lens element adjacent to the optical axis is convex
in principle. If the lens element has a concave surface, the
surface of the lens element adjacent to the optical axis is concave
in principle.
[0092] The optical image capturing system of the disclosure can be
adapted to the optical image capturing system with automatic focus
if required. With the features of a good aberration correction and
a high quality of image formation, the optical image capturing
system can be used in various application fields.
[0093] The optical image capturing system of the disclosure can
include a driving module according to the actual requirements. The
driving module may be coupled with the lens elements to enable the
lens elements producing displacement. The driving module may be the
voice coil motor (VCM) which is applied to move the lens to focus,
or may be the optical image stabilization (OIS) which is applied to
reduce the distortion frequency owing to the vibration of the lens
while shooting.
[0094] At least one of the first, second, third, fourth, fifth and
sixth lens elements of the optical image capturing system of the
disclosure may further be designed as a light filtration element
with a wavelength of less than 500 nm according to the actual
requirement. The light filter element may be made by coating at
least one surface of the specific lens element characterized of the
filter function, and alternatively, may be made by the lens element
per se made of the material which is capable of filtering short
wavelength.
[0095] The image plane of the optical image capturing system
according to the present application may be a plane or a curved
surface based on the actual requirement. When the image plane is a
curved surface such as a spherical surface with a radius of
curvature, the angle of incidence which is necessary for focusing
light on the image plane can be reduced. Hence, it not only
contributes to shortening the length of the optical image capturing
system, but also to promote the relative illuminance.

plane by 0.7 HOI according to the fourth embodiment of the present
application. As shown in FIG. 4A, in order from an object side to
an image side, the optical image capturing system includes an
aperture stop 400, a first lens element 410, a second lens element
420, a third lens element 430, a fourth lens element 440, a fifth
lens element 450, a sixth lens element 460, an IR-bandstop filter
480, an image plane 490, and an image sensing device 492.
[0185] The first lens element 410 has positive refractive power and
it is made of plastic material. The first lens element 410 has a
convex object-side surface 412 and a concave image-side surface
414, and both of the object-side surface 412 and the image-side
surface 414 are aspheric and have one inflection point.
[0186] The second lens element 420 has negative refractive power
and it is made of plastic material. The second lens element 420 has
a convex object-side surface 422 and a concave image-side surface
424, and both of the object-side surface 422 and the image-side
surface 424 are aspheric and have one inflection point.
[0187] The third lens element 430 has negative refractive power and
it is made of plastic material. The third lens element 430 has a
convex object-side surface 432 and a concave image-side surface
434, and both of the object-side surface 432 and the image-side
surface 434 are aspheric and have two inflection points.
[0188] The fourth lens element 440 has positive refractive power
and it is made of plastic material. The fourth lens element 440 has
a convex object-side surface 442 and a convex image-side surface

The Fifth Embodiment (Embodiment 5)
[0197] Please refer to FIG. 5A, FIG. 5B and FIG. 5C, FIG. 5A is a
schematic view of the optical image capturing system according to
the fifth embodiment of the present application, FIG. 5B is
longitudinal spherical aberration curves, astigmatic field curves,
and an optical distortion curve of the optical image capturing
system in the order from left to right according to the fifth
embodiment of the present application, and FIG. 5C is a lateral
aberration diagram of tangential fan, sagittal fan, the longest
operation wavelength and the shortest operation wavelength passing
through an edge of the entrance pupil and incident on the image
plane by 0.7 HOI according to the fifth embodiment of the present
application. As shown in FIG. 5A, in order from an object side to
an image side, the optical image capturing system includes an
aperture stop 500, a first lens element 510, a second lens element
520, a third lens element 530, a fourth lens element 540, a fifth
lens element 550, a sixth lens element 560, an IR-bandstop filter
580, an image plane 590, and an image sensing device 592.
[0198] The first lens element 510 has positive refractive power and
it is made of plastic material. The first lens element 510 has a
convex object-side surface 512 and a concave image-side surface
514, and both of the object-side surface 512 and the image-side
surface 514 are aspheric and have one inflection point.
[0199] The second lens element 520 has negative refractive power
and it is made of plastic material. The second lens element 520 has
a convex object-side surface 522 and a concave image-side surface
524, and both of the object-side surface 522 and the image-side
surface 524 are aspheric and have one inflection point.
[0200] The third lens element 530 has negative refractive power and
it is made of plastic material. The third lens element 530 has a
convex object-side surface 532 and a concave image-side surface
534, and both of the object-side surface 532 and the image-side
surface 534 are aspheric and have two inflection points.
[0201] The fourth lens element 540 has positive refractive power
and it is made of plastic material. The fourth lens element 540 has
a convex object-side surface 542 and a convex image-side surface
544, and both of the object-side surface 542 and the image-side
surface 544 are aspheric. The object-side surface 542 has two
inflection points and the image-side surface 544 has one inflection
point.
[0202] The fifth lens element 550 has positive refractive power and
it is made of plastic material. The fifth lens element 550 has a
concave object-side surface 552 and a convex image-side surface
554, and both of the object-side surface 552 and the image-side
surface 554 are aspheric and have two inflection points.
[0203] The sixth lens element 560 has negative refractive power and
it is made of plastic material. The sixth lens element 560 has a
convex object-side surface 562 and a concave image-side surface
564. The object-side surface 562 and the image-side surface 564
both have one inflection point. Hereby, the back focal length is
reduced to miniaturize the lens element effectively. In addition,
the angle of incident with incoming light from an off-axis view
field can be suppressed effectively and the aberration in the
off-axis view field can be corrected further.
[0204] The IR-bandstop filter 580 is made of glass material without
affecting the focal length of the optical image capturing system
and it is disposed between the sixth lens element 560 and the image
plane 590.
[0205] Please refer to the following Table 9 and Table 10.

The Sixth Embodiment (Embodiment 6)
[0210] Please refer to FIG. 6A, FIG. 6B and FIG. 6C, FIG. 6A is a
schematic view of the optical image capturing system according to
the sixth Embodiment of the present application, FIG. 6B is
longitudinal spherical aberration curves, astigmatic field curves,
and an optical distortion curve of the optical image capturing
system in the order from left to right according to the sixth
Embodiment of the present application, and FIG. 6C is a lateral
aberration diagram of tangential fan, sagittal fan, the longest
operation wavelength and the shortest operation wavelength passing
through an edge of the entrance pupil and incident on the image
plane by 0.7 HOI according to the sixth embodiment of the present
application. As shown in FIG. 6A, in order from an object side to
an image side, the optical image capturing system includes an
aperture stop 600, a first lens element 610, a second lens element
620, a third lens element 630, a fourth lens element 640, a fifth
lens element 650, a sixth lens element 660, an IR-bandstop filter
680, an image plane 690, and an image sensing device 692.
[0211] The first lens element 610 has positive refractive power and
it is made of plastic material. The first lens element 610 has a
convex object-side surface 612 and a concave image-side surface
614, and both of the object-side surface 612 and the image-side
surface 614 are aspheric and have one inflection point.
[0212] The second lens element 620 has negative refractive power
and it is made of plastic material. The second lens element 620 has
a convex object-side surface 622 and a concave image-side surface
624, and both of the object-side surface 622 and the image-side
surface 624 are aspheric and have an inflection point.
[0213] The third lens element 630 has negative refractive power and
it is made of plastic material. The third lens element 630 has a
convex object-side surface 632 and a concave image-side surface
634, and both of the object-side surface 632 and the image-side
surface 634 are aspheric. The object-side surface 632 has one
inflection point and the image-side surface 634 has two inflection
points.
[0214] The fourth lens element 640 has positive refractive power
and it is made of plastic material. The fourth lens element 640 has
a convex object-side surface 642 and a concave image-side surface
644, and both of the object-side surface 642 and the image-side
surface 644 are aspheric and have one inflection point.
[0215] The fifth lens element 650 has positive refractive power and
it is made of plastic material. The fifth lens element 650 has a
concave object-side surface 652 and a convex image-side surface
654, and both of the object-side surface 652 and the image-side
surface 654 are aspheric and have two inflection points.
[0216] The sixth lens element 660 has negative refractive power and
it is made of plastic material. The sixth lens element 660 has a
convex object-side surface 662 and a concave image-side surface
664. The object-side surface 662 and the image-side surface 664
both have one inflection point. Hereby, the back focal length is
reduced to miniaturize the lens element effectively. In addition,
the angle of incident with incoming light from an off-axis view
field can be suppressed effectively and the aberration in the
off-axis view field can be corrected further.
[0217] The IR-bandstop filter 680 is made of plastic material
without affecting the focal length of the optical image capturing
system and it is disposed between the sixth lens element 660 and
the image plane 690.
[0218] Please refer to the following Table 11 and Table 12.
The detailed data of the optical image capturing system of the
sixth Embodiment is as shown in Table 11.

[0223] Please refer to FIG. 7A, FIG. 7B and FIG. 7C, FIG. 7A is a
schematic view of the optical image capturing system according to
the seventh Embodiment of the present application, FIG. 7B is
longitudinal spherical aberration curves, astigmatic field curves,
and an optical distortion curve of the optical image capturing
system in the order from left to right according to the seventh
Embodiment of the present application, and FIG. 7C is a lateral
aberration diagram of tangential fan, sagittal fan, the longest
operation wavelength and the shortest operation wavelength passing
through an edge of the entrance pupil and incident on the image
plane by 0.7 HOI according to the seventh embodiment of the present
application. As shown in FIG. 7A, in order from an object side to
an image side, the optical image capturing system includes an
aperture stop 700, a first lens element 710, a second lens element
720, a third lens element 730, a fourth lens element 740, a fifth
lens element 750, a sixth lens element 760, an IR-bandstop filter
780, an image plane 790, and an image sensing device 792.
[0224] The first lens element 710 has positive refractive power and
it is made of plastic material. The first lens element 710 has a
convex object-side surface 712 and a concave image-side surface
714, and both of the object-side surface 712 and the image-side
surface 714 are aspheric. The object-side surface 712 has one
inflection point and the image-side surface 714 has two inflection
points.
[0225] The second lens element 720 has positive refractive power
and it is made of plastic material. The second lens element 720 has
a convex object-side surface 722 and a convex image-side surface
724, and both of the object-side surface 722 and the image-side
surface 724 are aspheric. The object-side surface 722 has two
inflection points.
[0226] The third lens element 730 has negative refractive power and
it is made of plastic material. The third lens element 730 has a
convex object-side surface 732 and a concave image-side surface
734, and both of the object-side surface 732 and the image-side
surface 734 are aspheric and have one inflection point.
[0227] The fourth lens element 740 has positive refractive power
and it is made of plastic material. The fourth lens element 740 has
a convex object-side surface 742 and a concave image-side surface
744, and both of the object-side surface 742 and the image-side
surface 744 are aspheric. The object-side surface 742 has three

[0229] The sixth lens element 760 has negative refractive power and
it is made of plastic material. The sixth lens element 760 has a
convex object-side surface 762 and a concave image-side surface
764. The object-side surface 762 has two inflection points and the
image-side surface 764 has one inflection point. Hereby, the back
focal length is reduced to miniaturize the lens element
effectively. In addition, the angle of incident with incoming light
from an off-axis view field can be suppressed effectively and the
aberration in the off-axis view field can be corrected further.
[0230] The IR-bandstop filter 780 is made of glass material without
affecting the focal length of the optical image capturing system
and it is disposed between the sixth lens element 760 and the image
plane 790.
