The application is further described below in conjunction with specific embodiment.
There are such as six lens according to the pick-up lens of the application illustrative embodiments, that is, the first lens, second are thoroughly Mirror, the third lens, the 4th lens, the 5th lens and the 6th lens.This six lens is arranged successively along optical axis from object side to image side.
According to the embodiment, the first lens have positive light coke, and object side is convex surface.Second lens have negative light focus Degree, image side surface are concave surface.The third lens have positive light coke；4th lens have positive light coke or negative power, image side Face is convex surface.5th lens have positive light coke or negative power.6th lens have negative power, and its image side surface is close At axis be concave surface, and have at least one point of inflexion, i.e., the lens from the center to edge exist by concave change it is convex or by concave change it is convex again Become recessed variation tendency.
It can according to the total effective focal length f and Entry pupil diameters EPD of the above-mentioned pick-up lens of the application illustrative embodiments Meet f/EPD≤1.8, for example, 1.69≤f/EPD≤1.8.This can make system have big light during increasing light passing amount Circle advantage, thus imaging effect while reducing the aberration of peripheral field under enhancing dark situation.Optionally, first lens Effective pixel area diagonal line length on the imaging surface of distance TTL and pick-up lens on object side to the axis of the imaging surface of pick-up lens Half ImgH can meet TTL/ImgH≤1.6, for example, 1.53≤TTL/ImgH≤1.6.This can effectively compress pick-up lens Overall size, to guarantee ultra-slim features and the miniaturization of pick-up lens.
In the exemplary embodiment, it may be provided with aperture diaphragm between the first lens and the second lens.Aperture diaphragm Distance on the object side of distance SL and the first lens to the axis of the imaging surface of pick-up lens on to the axis of the imaging surface of pick-up lens TTL can meet 0.7≤SL/TTL≤0.9, for example, 0.76≤SL/TTL≤0.86.Using aperture diaphragm as a design variable It is arranged between the first lens and the second lens, can effectively increases system anaberration ability.
The maximum effective radius of the image side surface of the maximum effective radius DT11 and the second lens of the object side of first lens DT22 can meet 0.1≤DT11/DT22≤1.6, for example, DT11 and DT22 can further meet 1.19≤DT11/DT22≤ 1.51.Light passing constrains the bore of the first lens and the second lens, so that optical system front end bore is smaller, so as to effectively subtract The front opening of small mould group.
In addition, the radius of curvature R 1 of the object side of the first lens and the radius of curvature R 4 of the image side surface of the second lens can meet 0 < R1/R4 < 1.5, such as R1 and R4 can further meet 0.49≤R1/R4≤1.08.Pass through the object of the first lens of reasonable disposition The radius of curvature R 4 of the image side surface of the radius of curvature R 1 and the second lens of side, using the first lens and the second lens as a light Group designs, so as to effectively increasing the anastigmatic ability of system.
The effective focal length f1 of first lens and the effective focal length f3 of the third lens can meet 0.2 < f1/f3 < 0.8, for example, f1 0.32≤f1/f3≤0.65 can further be met with f3.Pass through the effective focal length f1 and the third lens of the first lens of reasonable disposition Effective focal length f3 the first lens and the third lens can be made reasonably to undertake deflection angle, to reduce the primary aberration of system.
The effective focal length f3 of the third lens and the effective focal length f4 of the 4th lens can meet -0.2 < f3/f4≤2.1, for example, F3 and f4 can further meet -0.13≤f3/f4≤2.02.As it is known to the person skilled in the art, spherical aberration is limitation lens point One of most important factor of resolution can effectively balance spherical aberration in this application by the negative lens of the reasonable focal power of introducing, To effectively improve image quality.
The combined focal length f45 of the total effective focal length f and the 4th lens and the 5th lens of pick-up lens can meet | f/f45 |≤ 1.3, for example, f and f45 can further meet 0.1≤| f/f45 |≤1.23.Pass through the 4th lens of reasonable disposition and the 5th lens Combined focal length, can make optical system have preferable flat field Qu Nengli.
In the application, the thickness of each lens can be optimized.For example, the center thickness CT1 and third of the first lens are saturating The center thickness CT3 of mirror can meet 1.0≤CT1/CT3≤2.0, for example, 1.07≤CT1/CT3≤1.99.Pass through reasonable disposition The center thickness CT1 of the first lens and center thickness CT3 of the third lens can make pick-up lens guarantee the same of miniaturization When the ability with the distortion that preferably disappears.In another example the center thickness CT5 of the center thickness CT3 of the third lens, the 5th lens with And the 6th the center thickness CT6 of lens can meet 0.4≤CT3/ (CT5+CT6)≤0.7, for example, 0.46≤CT3/ (CT5+CT6) ≤0.68.By the center thickness of each lens of reasonable disposition, the ability that can make pick-up lens that there is the distortion that preferably disappears.
In addition, can also be optimized to the airspace distance between each lens on optical axis.For example, the 5th lens and The center thickness CT6 of airspace T56 and sixth lens of six lens on optical axis can meet 0.3≤T56/CT6≤0.8, example Such as, 0.35≤T56/CT6≤0.75.By the airspace of the 5th lens of reasonable disposition and the 6th lens on optical axis, can have The size of effect ground compression pick-up lens, to guarantee the ultra-slim features of pick-up lens.In order to guarantee that pick-up lens can be easier to The matching on ground and conventional chip needs the radius of curvature of the image side surface of the 6th lens of reasonable disposition.For example, pick-up lens always has The radius of curvature R 12 of the image side surface of effect focal length f and the 6th lens can meet 2.5 < f/R12 < 4.0, for example, f and R12 further may be used Meet 2.55≤f/R12≤3.66.
Multi-disc eyeglass, such as described above six can be used according to the pick-up lens of the above embodiment of the application. By spacing on the axis between each power of lens of reasonable distribution, face type, each lens etc., the view of pick-up lens can be effectively increased Angle guarantees the miniaturization of camera lens and improves image quality, so that pick-up lens is more advantageous to production and processing and applicable In portable electronic product.In presently filed embodiment, at least one of mirror surface of each lens is aspherical mirror.It is non- The characteristics of spherical lens, is: being consecutive variations from lens centre to periphery curvature.And have certain song from lens centre to periphery The spherical lens of rate is different, and non-spherical lens has more preferably radius of curvature characteristic, and there is improvement to distort aberration and improve astigmatism The advantages of aberration, enables to the visual field to become much larger and true.After non-spherical lens, it can eliminate and be imaged as much as possible When the aberration that occurs, so as to improve image quality.
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 composition quantity of camera lens can be changed, to obtain each result and advantage described below.Although for example, in embodiments It is described by taking six lens as an example, but the pick-up lens is not limited to include six lens.If desired, the pick-up lens It may also include the lens of other quantity.
The specific implementation for being applicable to the pick-up lens of above embodiment is further described referring to Fig. 1 to Figure 24 D Example.
