Abstract
The utility model provides a mini-sized camera lens comprising, from an object space to an image space, five lenses sequentially. A first lens is a lens having a positive focal power and a side-protruding object surface, a fourth lens is a lens having a positive focal power and a side-protruding image surface, and a fifth lens is a biconcave lens having a negative focal power. The lenses satisfy the following formula:|f2.3.4.5|/f>3, wherein | f2.3.4.5| is an absolute value of a combination focal length of the second, the third, the fourth, and the fifth lenses, and the f is a focal length of the whole system; also satisfy f 2.3.4/f<0.7, wherein f 2.3.4 is the combination focal length of the second, the third, and the fourth lenses, and the f is the focal length of the whole system. The utility model is advantageous in that the contradiction between the resolving power and the lens size can be solved, and the requirement of the high definition thin type can be satisfied.
Description
Technical field
The utility model relates to a kind of imaging optical system, particularly about a kind of miniature imaging lens combination that is applied to mobile phone camera.
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 is because size is little, and eyeglass quantity is also fewer, can't satisfy high-quality parsing requirement, certainly will will increase like this quantity of eyeglass, makes simultaneously Lens also larger, a contradiction so just occurred.Publication number is " CN101046542 ", the utility model patent that was called " imaging lens system " in open day for " 2007.10.03 ", 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 positive diopter the 3rd lens, have negative dioptric the 4th lens and have dioptric the 5th lens of plus or minus and consist of.Although this system solves the contradiction of understanding between image force and Lens, reached the slim requirement of high-resolution, but also have some undesirable places: it is less that the shape of the 5th lens has determined that Lens can't be done, and rear lens focus is longer apart from what also be difficult to do; The wave-like eyeglass of the 4th lens and the 5th lens is unfavorable for processing; Each organize that focal power between lens is distributed and eccentric tolerance between can't obtain better balance, therefore also there is the difficulty in unfavorable and processing in some designs.
The utility model content
The utility model has adopted five 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.
Described camera lens comprises five lens from the object side to the image side successively, and first lens is the protruding eyeglass of object plane side of positive light coke, and the 4th lens are the protruding eyeglass of image planes side of positive light coke, and the 5th lens are the eyeglass of the concave-concave shape of negative power; Described lens satisfy following formula:
|f2.3.4.5|/f＞3
Wherein, | f2.3.4.5| is the absolute value of the combined focal length of the 2nd, 3,4,5 lens; F is the focal length of whole system;
f2.3.4/f＜0.7
Wherein, f2.3.4 is the combined focal length of the 2nd, 3,4 eyeglasses; F is the focal length of whole system.
0.45<(∑CT)/Td<0.76
Wherein, ∑ CT is the thickness summation of the lens of all tool focal powers on optical axis; Td is the distance of picture side of thing side to the five eyeglasses of the first eyeglass.
The diaphragm of described camera lens is arranged between first lens and the second lens.
It is aspheric surface that described camera lens has a face at least.
The eyeglass material of described camera lens is plastics.
The micro pick-up lens that the utility model provides distributes by different focal powers, realizes good optical characteristics, can be installed on easily in the digital product of all kinds of portable image requirements.
