Abstract
Disclosed is a mobile phone image capturing lens group. The mobile phone image capturing lens group comprises a lens group and is characterized in that the lens group comprises a first lens, a second lens, a third lens and a diaphragm which are successively coaxially arranged from an object side to an image side, wherein the first lens and the third lens are double-convex lenses, the second lens is a double-concave lens, and the diaphragm is arranged between the second lens and the third lens. According to the mobile phone image capturing lens group provided by the invention, through reasonable structure type selection and optimization design and full consideration of the requirements of a processing process and the structure cost, the obtained mobile phone lens group is simple in structure. The product is reasonable in design and high in practicality, thereby having quite good market prospect.
Description
Technical field
The present invention relates to a kind of mobile phone taking lens group, belong to mobile phone optical technical field.
Background technology
Mobile lens, as the accessory of mobile phone, requires that it can meet the pixel index needed for mobile phone on the one hand, also requires that it is different from other independent lens on the other hand, needs strictly to control cost.Therefore, how to design good processability, material is cheap, and less eyeglass number, mobile lens lens combination easy to assembly, becomes the key designing this kind of camera lens.
Summary of the invention
According to above-mentioned requirements, the object of this invention is to provide a kind of mobile phone taking lens group, by rational structure model selection and optimal design, and take into full account processing technology and infrastructure cost requirement, the simple mobile lens lens combination of a kind of structure of acquisition.This product design is reasonable, practical, has good market outlook.
For achieving the above object, the present invention is realized by following technological means:
A kind of mobile phone taking lens group, comprise lens combination, it is characterized in that: described lens combination comprises the first lens, the second lens, the 3rd lens and the diaphragm that are coaxially arranged in order from object space to image space, described first lens, the 3rd lens are biconvex lens, described second lens are biconcave lens, and described diaphragm is placed between the second lens and the 3rd lens.
Further:
The two sides of described first lens, the second lens and the 3rd lens is sphere.
The refractive index of described first lens, the second lens and the 3rd lens is all little by 1.7.
The focal length 4.5mm of described lens combination.
The field angle of described lens combination 56 degree.
The backscatter extinction logarithmic ratio that blocks of described lens combination is within 50%.
The invention has the beneficial effects as follows: a kind of mobile phone taking lens group provided by the invention, by rational structure model selection and optimal design, and takes into full account processing technology and infrastructure cost requirement, obtains the simple mobile lens lens combination of a kind of structure.This product design is reasonable, practical, has good market outlook.
Accompanying drawing explanation
Fig. 1 the design structural representation.
