Detailed description of the invention

For further illustrating each embodiment, the present invention is provided with accompanying drawing.These accompanying drawings are the invention discloses content one Point, it is mainly that embodiment is described, and the associated description of description can be coordinated to explain the operation principles of embodiment.Coordinate With reference to these contents, one skilled in the art will be understood that other possible embodiments and advantages of the present invention. Assembly in figure is not necessarily to scale, and similar element numbers is conventionally used to indicate similar assembly.

" lens have positive refractive index (or negative refractive index) " that this description is sayed, refers to that described lens are positioned at optical axis For near zone has positive refractive index (or negative refractive index)." the thing side (or image side surface) of lens includes being positioned at certain region Convex surface part (or concave part) ", refer to this region compared to the exterior lateral area being radially close to this region, towards being parallel to optical axis For direction more " outwardly convex " (or " caving inward ").As a example by Fig. 1, wherein I is optical axis and this lens are with this light Axle I is that axis of symmetry is radially symmetrical, and the thing side of these lens has convex surface part in a-quadrant, B region has concave part and C Region has convex surface part, and reason is a-quadrant compared to the exterior lateral area (i.e. B region) being radially close to this region, towards parallel In the direction of optical axis more outwardly convex, B region then more caves inward compared to C region, and C region is compared to E region also In like manner more outwardly convex." it is positioned at circumference near zone ", refers to be positioned on lens and be intended for curved surface that imaging light passes through Being positioned at circumference near zone, that is the C region in figure, wherein, imaging light includes chief ray (chief ray) Lc and edge Light (marginal ray) Lm." it is positioned at optical axis near zone " and refers to that this is intended near the optical axis of the curved surface that imaging light passes through A-quadrant in region, that is figure.Additionally, these lens also comprise an extension E, it is loaded on an optical imagery with for this battery of lens In camera lens, preferable imaging light can't be by this extension E, but the structure of this extension E and shape are not limited to this, with Under embodiment be ask accompanying drawing the most all eliminate part extension.

The optical imaging lens of the present invention, is a tight shot, and is sequentially to be arranged along an optical axis by from thing side to image side One first lens, one second lens, one the 3rd lens, an aperture, one the 4th lens and one the 5th lens constituted, Mei Yitou Mirror all has refractive index, and has a thing side towards thing side and making imaging light pass through and and towards image side and make imaging The image side surface that light passes through.The optical imaging lens of the present invention only has aforementioned five lens with refractive index altogether, by setting Count the detail characteristic of each lens, and broad shooting angle and good optical property can be provided.The detail characteristic of each lens is such as Under: the first lens have negative refractive index, and image side surface has a concave part being positioned at optical axis near zone；The thing side of the second lens Mask has a convex surface part being positioned at circumference near zone；The image side surface of the 3rd lens has a convex surface being positioned at circumference near zone Portion；And the 5th the thing side of lens there is a convex surface part being positioned at optical axis near zone, and its material is plastics.

The characteristic of the aforementioned each eyeglass designed at this mainly considers optical characteristics and the lens length of optical imaging lens, For example: the first lens have negative refractive index, the light contributing to wide-angle enters camera lens, can help to receive light.Aperture is placed in Between three lens and the 4th lens, contribute to strengthening the angle of visual field.Be collocated with each other be formed on the first lens image side surface be positioned at light The concave part of axle near zone, the convex surface part being positioned at circumference near zone being formed on the second lens thing side, it is formed at The convex surface part being positioned at circumference near zone on three lens image side surface and be formed on the 5th lens thing side to be positioned at optical axis attached The concave-convex surface designs such as the convex surface part of near field, contribute to revising aberration, help to maintain good optical property.Additionally, the 5th Lens material is that plastics can lower weight and reduce cost.Therefore, common aforementioned detailing of arranging in pairs or groups, the present invention can reach raising The effect of the image quality of system.
