DETAILED DESCRIPTION OF THE INVENTION
(29) An optical image capturing module of the present invention includes a structural design and an optical design, wherein structural embodiments will be described first.
(30) As shown in
(31) The lens assembly includes a lens base LB1, a lens group L, and an IR-cut filter IR1. In the current embodiment, the lens base LB1 is made of plastic material and is opaque, and includes a lens holder LH1 and a lens barrel B1. More specifically, the lens holder LH1 has a predetermined thickness TH1, and a maximum value of a minimum length on a periphery of the lens holder LH1 perpendicular to the optical axis of the lens group L is denoted by PhiD. In addition, the lens holder LH1 has a lower through hole DH1 penetrating through both ends of the lens holder LH1 to be hollow, and is fixed on the carrier board CB, so that the image sensing component S directly faces the lower through hole DH1. The lens barrel B1 has a predetermined thickness TH2, and a maximum value of a minimum length on a periphery of the lens barrel B1 perpendicular to the optical axis of the lens group L is denoted by PhiC. Moreover, the lens barrel B1 is disposed in the lens holder LH1 to be located in the lower through hole DH1, and has an upper through hole UH1 penetrating through both ends of the lens barrel B1, so that the upper through hole UH1 communicates with the lower through hole DH1 to form a receiving hole, wherein the upper through hole UH1 of the lens barrel B1 directly faces the sensing surface of the image sensing component S.
(32) The lens group L includes at least two lenses with refractive power, and optical embodiments will be described in detail later. The lens group L is disposed on the lens barrel B1 of the lens base LB1 and is located in the upper through hole UH1. In addition, an image plane of the lens group L is located on the sensing surface of the image sensing component S, wherein the optical axis of the lens group L overlaps with a central normal of the sensing surface, so that light could pass through the lens group L in the receiving hole and could be projected onto the sensing surface. Moreover, a maximum diameter of an image-side surface of a lens of the lens group L closest to the image plane is denoted by PhiB, and a maximum effective diameter of the image-side surface of the lens of the lens group L closest to the image plane (i.e., the image space) could be also called optical exit pupil, and is denoted by PhiA.
(33) The IR-cut filter IR1 is fixed on the lens holder LH1 of the lens base LB1 and is located in the receiving hole and is located between the lens group L and the image sensing component S, thereby to filter out an excess infrared in the image light passing through the lens group L, enhancing the image quality.
(34) It is worth mentioning that, in order to overlap the optical axis of the lens group L with the central normal of the sensing surface of the image sensing component S, an outer side of the lens barrel B1 of the optical image capturing module of the current embodiment is not completely in contact with an inner periphery of the lens holder LH1, thereby to leave a slight gap, so that a curable glue could be coated between the lens holder LH1 and the lens barrel B1 in advance, and the optical axis of the lens group L and the central normal of the image sensing component S could be adjusted to be overlapped with each other, and then the curable glue is cured to fix the lens barrel B1 to the lens holder LH1, that is, an active alignment assembly is carried out.

The plastic lenses may reduce the weight and lower the cost of the optical image capturing module, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the optical image capturing module. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that could obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the optical image capturing module.

(77) The optical image capturing module of the present invention could further include a driving module to meet different demands, wherein the driving module could be coupled with the lenses to move the lenses. The driving module could be a voice coil motor (VCM), which is used to move the lens for focusing, or could be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.
(78) To meet different requirements, at least one lens among the first lens to the seventh lens of the optical image capturing module of the present invention could be a light filter, which filters out light of wavelength shorter than 500 nm. Such effect could be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.
(79) To meet different requirements, the image plane of the optical image capturing module in the present invention could be either flat or curved. If the image plane is curved (e.g., a sphere with a radius of curvature), the incidence angle required for focusing light on the image plane could be decreased, which is not only helpful to shorten the length of the optical image capturing module (TTL), but also helpful to increase the relative illuminance.
(80) We provide several optical embodiments in conjunction with the accompanying drawings for the best understanding. In practice, the optical embodiments of the present invention could be applied to other structural embodiments.

Whereby, the incident angle of each view field entering the sixth lens 260 could be effectively adjusted to improve aberration.
(152) The seventh lens 270 has negative refractive power and is made of glass. An object-side surface 272, which faces the object side, is a convex surface, and an image-side surface 274, which faces the image side, is a convex surface. It may help to shorten the back focal length to keep small in size, and may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.
(153) The IR-cut filter 280 is made of glass and is disposed between the seventh lens 270 and the image plane 290. The IR-cut filter 280 gives no contribution to the focal length of the optical image capturing module.

(165) The first lens 310 has negative refractive power and is made of glass. An object-side surface 312 thereof, which faces the object side, is a convex spherical surface, and an image-side surface 314 thereof, which faces the image side, is a concave spherical surface.
(166) The second lens 320 has negative refractive power and is made of glass. An object-side surface 322 thereof, which faces the object side, is a concave spherical surface, and an image-side surface 324 thereof, which faces the image side, is a convex spherical surface.
(167) The third lens 330 has positive refractive power and is made of plastic. An object-side surface 332 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 334 thereof, which faces the image side, is a convex aspheric surface. The image-side surface 334 has an inflection point.
(168) The fourth lens 340 has negative refractive power and is made of plastic. An object-side surface 342, which faces the object side, is a concave aspheric surface, and an image-side surface 344, which faces the image side, is a concave aspheric surface. The image-side surface 344 has an inflection point.
(169) The fifth lens 350 has positive refractive power and is made of plastic. An object-side surface 352, which faces the object side, is a convex aspheric surface, and an image-side surface 354, which faces the image side, is a convex aspheric surface.

(217) The second lens 620 has negative refractive power and is made of plastic. An object-side surface 622 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 624 thereof, which faces the image side, is a convex aspheric surface. The image-side surface 624 has an inflection point.
(218) The third lens 630 has positive refractive power and is made of plastic. An object-side surface 632, which faces the object side, is a convex aspheric surface, and an image-side surface 634, which faces the image side, is a concave aspheric surface. The object-side surface 632 has two inflection points, and the image-side surface 634 has an inflection point.
