In the application, the radius of curvature of each minute surface can be optimized.For example, the radius of curvature of the thing side of the first lens - 1.0 ＜ (R1+R2)/(R1-R2) ＜ 0, R1 and R2 can be met between the radius of curvature R 2 of the image side surface of R1 and the first lens and enters one Step can meet -0.84≤(R1+R2)/(R1-R2)≤- 0.61.By the curvature range of the lens of reasonable disposition first, come effectively Control the astigmatism amount of optical system.Again for example, the image side surface of the lens of radius of curvature R 5 and the 3rd of the thing side of the 3rd lens - 1.0 ＜ R5/R6 ＜ 0 can be met between radius of curvature R 6, more specifically, R5 and R6 can further meet -0.98≤R5/R6≤- 0.60.The curvature of field of optical system is efficiently controlled by controlling the curvature bending direction of middle 3rd lens, so as to lifted be The image quality of system.

In order to efficiently control the amount of distortion of system, the center thickness of the 5th lens can reasonably be configured. 7.0≤f/CT5 ＜ 9.0 can be met between total effective focal length f and the center thickness CT5 of the 5th lens of imaging lens, more specifically Ground, f and CT5 can further meet 7.07≤f/CT5≤8.30.

Additionally, the thing side of the first lens to imaging lens imaging surface on optical axis apart from TTL and imaging lens The half ImgH of effective pixel area diagonal line length can meet TTL/ImgH≤1.6 on imaging surface, for example, TTL and ImgH enters one Step can meet 1.37≤TTL/ImgH≤1.45.By the optics total length to camera lens and as a high proportion of control, can be effectively The overall size of imaging lens is compressed, to realize ultra-slim features and the miniaturization of imaging lens, so that above-mentioned imaging lens energy It is enough to be preferably applied to such as limited system of portable type electronic product equidimension.

In the exemplary embodiment, imaging lens are also provided with the aperture STO for confine optical beam, to adjust entering light Amount.It will be apparent to a skilled person that aperture STO can be arranged as required at any lens position, i.e. aperture The setting of STO should not be limited to the position shown in accompanying drawing.

The imaging lens of the above-mentioned implementation method according to the application can use multi-disc eyeglass, such as mentioned above five. By spacing on each power of lens of reasonable distribution, the axle between face type, the center thickness of each lens and each lens etc., can Effectively expand the aperture of imaging lens, reduce system sensitivity, ensure the miniaturization of camera lens and improve image quality, so that Imaging lens are more beneficial for producing and processing and being applicable to portable type electronic product.It is each in presently filed embodiment At least one of minute surface of mirror is aspherical mirror.The characteristics of non-spherical lens is：Curvature is to connect from lens centre to periphery Continuous change.Different from the spherical lens for having constant curvature from lens centre to periphery, non-spherical lens has more preferably curvature Radius characteristic, has the advantages that to improve and distorts aberration and improve astigmatic image error, enables to the visual field to become much larger and true.Using After non-spherical lens, the aberration occurred when imaging can be as much as possible eliminated, so as to improve image quality.In addition, non- The use of spherical lens can also efficiently reduce the lens number in optical system.

However, it will be understood by those of skill in the art that without departing from this application claims technical scheme situation Under, the lens numbers of composition camera lens can be changed to obtain each result and the advantage described in this specification.For example, although It is described by taking five lens as an example in implementation method, but the imaging lens are not limited to include five lens.If desired, The imaging lens may also include the lens of other quantity.

The specific embodiment of the imaging lens for being applicable to above-mentioned implementation method is further described with reference to the accompanying drawings.
