Abstract
The invention provides a miniature pick-up lens, comprising a first lens group and a second lens group from an object side to an image side in sequence. The first lens group comprises a first lens with positive power, a second lens with negative power, a third lens with positive power from an object side to an image side in sequence. An object side of the first lens is a convex surface, and an image side surface is provided with at least an inflection point. An image side surface of the third lens is a convex surface. The second lens group comprises a fourth lens with positive power and a fifth lens with negative power from an object side to an image side in sequence. An object side surface of the fourth lens is a concave surface. An paraxial image side surface is a concave surface, and satisfies 18.0<=(D6/TTL)x100<=21.5, wherein D6 is a distance between the first lens group and the second lens group on an optical axis, and TTL is overall length of the lenses. The miniature pick-up lens uses five plastic aspheric lenses, and through different focal power distribution, the lens is realized to be miniaturized, and meanwhile the lens has better imaging quality.
Description
Technical field
The present invention relates to a kind of micro pick-up lens, the miniature imaging lens combination that is formed by five groups of lens.
Background technology
Along with the development of CMOS chip technology, the Pixel Dimensions of chip is more and more less, and is also more and more higher to the imaging of optical systems quality requirements that matches at present, and the optical lens size of mobile phone or digital camera but becomes more and more less; General slim camera lens certainly will will increase the quantity of eyeglass like this because size is little, and eyeglass quantity is also fewer, can't satisfy high-quality parsing requirement, so that the optics overall length of camera lens increases, is difficult to have concurrently the characteristic of miniaturization simultaneously.Publication number is " CN101876743 ", the patent of invention that was called " photographic lens group " in open day for " 2010.11.03 ", name, for this contradiction the optical imaging system that a kind of 5 groups of lens consist of has been proposed, five groups of lens in this camera lens from the object side to the image side successively by the first lens with positive diopter, have negative dioptric the second lens, have negative dioptric the 3rd lens, the 4th lens with positive diopter and the 5th lens and consist of.Although this system has effectively promoted image quality, kept simultaneously the characteristic of miniaturization, when pursuing miniaturization, these lens are the eccentric tolerance of balance better, so that the tolerance susceptibility is higher, it is shorter to have determined that thus this Lens can't be done.
Summary of the invention
Therefore, the present invention proposes that a kind of high-resolution is slim, the pick-up lens of low sensitivity, having solved camera lens has better image quality in miniaturization, and its technical scheme is as described below:
A kind of micro pick-up lens, to sequentially comprising first lens group and the second lens combination as side, described first lens group is extremely sequentially comprised as side by the thing side by the thing side:
The first lens of tool positive light coke, its thing side is convex surface, and as being provided with at least one point of inflexion on the side surface;
The second lens of tool negative power;
The 3rd lens of tool positive light coke, it is convex surface as the side;
Described the second mirror group is extremely sequentially comprised as side by the thing side:
The 4th lens of tool positive light coke, its thing side is concave surface;
The 5th lens of tool negative power, its paraxial place is concave surface as the side;
Described camera lens satisfies:
18.0≦(D6/TTL)*100≦21.5
Wherein, D6 is first mirror group and the spacing of the second mirror group on optical axis, and TTL is the overall length of lens.
Further, described camera lens satisfies
-1.0≦f1.2.3/f4.5≦-0.25
Wherein, f1.2.3 is the combined focal length of first mirror group, and f4.5 is the combined focal length of the second mirror group.
Further, described camera lens satisfies
-30<R7/R10<-6.5
Wherein, R7 be in the second mirror group near the thing side surface radius-of-curvature of the eyeglass of thing side, R10 is near the picture side surface radius-of-curvature of the eyeglass of picture side in the second mirror group.
Described camera lens is provided with the light hurdle before the first lens group.
It is aspheric surface that described camera lens has a face at least.
The present invention has adopted 5 plastic aspherical element eyeglasses, distributes by different focal powers, has overcome the defective of prior art, and present specification requirement and performance requirement have been proposed a kind of new solution.
