It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The application is further described below in conjunction with specific embodiment.
There are such as seven lens according to the pick-up lens of the application illustrative embodiments, i.e. the first lens, second are thoroughly Mirror, the third lens, the 4th lens, the 5th lens, the 6th lens and the 7th lens.This seven lens are along optical axis from object side to picture Side sequential.
In the exemplary embodiment, the first lens can have positive light coke, and object side is convex surface.Second lens can have There is positive light coke, object side is convex surface, and image side surface is also convex surface.The third lens can have negative power.4th lens have Positive light coke or negative power.5th lens have positive light coke or negative power.6th lens have positive light coke or negative light Focal power, image side surface are concave surface at paraxial place.7th lens can have negative power, and image side surface is concave surface at paraxial place.Separately Outside, the 7th lens can have at least one point of inflexion, i.e., the lens from the center to edge exist for example by concave change it is convex or by concave change It is convex to become recessed variation tendency again.
Entrance pupil according to total effective focal length f of the above-mentioned pick-up lens of the application illustrative embodiments and pick-up lens is straight Diameter EPD can meet f/EPD≤1.9, more specifically, total effective focal length f and Entry pupil diameters EPD can further meet, 1.79≤f/ EPD≤1.90.Pick-up lens is configured to meet f/EPD≤1.9, system can be made to have big during increasing light passing amount Aperture advantage, thus imaging effect while reducing the aberration of peripheral field under enhancing dark situation.
The object side of first lens to pick-up lens distance TTL and pick-up lens of the imaging surface on optical axis imaging surface The half ImgH of upper effective pixel area diagonal line length can meet TTL/ImgH≤1.7, for example, 1.49≤TTL/ImgH≤ 1.65.This can effectively compress the overall size of pick-up lens, to realize ultra-slim features and the miniaturization of pick-up lens.
In order to effectively balance color aberrations, the curvature of field, reduction light deflection angle, the susceptibility for reducing optical system are balanced, Can the effective focal length to each lens reasonably configured.For example, the effective focal length f1 of the first lens and the second lens is effective Focal length f2 can meet 0.5 < f1/f2 < 1.5, more specifically, f1 and f2 can further meet 0.86≤f1/f2≤1.32.Pass through conjunction Reason the first lens of configuration and the second power of lens can reduce the deflection angle of light, to reduce the susceptibility of system.Example again Such as, the effective focal length f2 of the second lens and the effective focal length f3 of the third lens can meet -2 < f2/f3 < 0, more specifically, f2 and f3 - 0.99≤f2/f3≤- 0.86 can further be met.As it is known to the person skilled in the art, spherical aberration is limitation lens efficiency One of most important factor can effectively balance spherical aberration, to have in this application by introducing the negative lens of reasonable focal power Effect ground promotes the image quality of pick-up lens.For another example total effective focal length f of the pick-up lens and effective focal length f1 of the first lens F/f1≤0.9 can be met, more specifically, f and f1 can further meet 0.66≤f/f1≤0.85.Pass through reasonable disposition camera lens Total effective focal length f of head, the ability that may make optical system that there is the preferable balance curvature of field.
In the application, the center thickness of each lens can be optimized.The center thickness CT1 and the second lens of first lens Center thickness CT2 between can meet 0.6 < CT1/CT2 < 1.5, more specifically, CT1 and CT2 can further meet 0.99≤ CT1/CT2≤1.09.It may make by the center thickness CT1 of the first lens of reasonable disposition and the center thickness CT2 of the second lens Ability of the pick-up lens with preferable balance aberration while guaranteeing miniaturization.The center thickness CT5 of 5th lens, the 6th 0.1 < CT5/ (CT6+CT7) < 0.8 can be met between the center thickness CT6 of lens and the center thickness CT7 of the 7th lens, more Body ground 0.26≤CT5/ (CT6+CT7)≤0.51.By the center thickness of each lens of reasonable disposition, it can guarantee miniaturization Meanwhile so that pick-up lens has the ability for the distortion that preferably disappears, to improve image quality.
In addition, can also be optimized to spacing on the axis between each lens.For example, the 6th lens and the 7th lens are in optical axis On airspace T67 and the center thickness CT7 of the 7th lens can meet 0.2 < T67/CT7 < 1, for example, T67 and CT7 are further 0.29≤T67/CT7≤0.52 can be met.It, can by the airspace of the 6th lens of reasonable disposition and the 7th lens on optical axis The size for effectively compressing pick-up lens, to guarantee the ultra-slim features of pick-up lens.
The maximum effective radius of the image side surface of the maximum effective radius DT11 and the third lens of the object side of first lens DT33 can meet 0.8 < DT11/DT33 < 1.5, more specifically, DT11 and DT33 can further meet 1.09≤DT11/DT33≤ 1.23.By the bore of constraint the first lens and the third lens, it may make optical system that there is appropriate lesser front end bore, from And effectively reduce the front opening of mould group.
In order to guarantee that pick-up lens can need the picture of the 7th lens of reasonable disposition relatively easily with the matching of conventional chip The radius of curvature of side.For example, the radius of curvature R 14 of the total effective focal length f and the image side surface of the 7th lens of pick-up lens can expire Foot 2.5 < f/R14 < 4.0, more specifically, f and R14 can further meet 2.91≤f/R14≤3.13.
Multi-disc eyeglass, such as described above seven can be used according to the pick-up lens of the above embodiment of the application. By each power of lens of reasonable distribution, face type, each lens center thickness and each lens between axis on spacing etc., can Effectively expand the aperture of pick-up lens, reduces system sensitivity, guarantees the miniaturization of camera lens and improve image quality, so that Pick-up lens, which is more advantageous to, to be produced and processed and is applicable to portable electronic product.It is each in presently filed embodiment At least one of mirror surface of mirror is aspherical mirror.The characteristics of non-spherical lens, is: being to connect from lens centre to periphery curvature Continuous variation.Different from there is the spherical lens of constant curvature from lens centre to periphery, non-spherical lens has more preferably curvature Radius characteristic has the advantages that 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 eliminated, as much as possible 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 solution the case where Under, the lens numbers for constituting camera lens can be changed, to obtain each result and advantage described in this specification.Although for example, It is described by taking seven lens as an example in embodiment, but the pick-up lens is not limited to include seven lens.If desired, The pick-up lens may also include the lens of other quantity.
The specific embodiment for being applicable to the optical lens of above embodiment is further described with reference to the accompanying drawings.
