Abstract
The utility model provides a cell -phone taking lens group, includes battery of lens, its characterized in that: the battery of lens includes from the coaxial first lens of arranging in proper order of object space to image space, second lens, third lens and diaphragm, first lens, third lens are the biconvex lens, the second lens are the biconcave lens, the diaphragm is arranged in between second lens and the third lens. The utility model provides a pair of cell -phone taking lens group is through reasonable structure lectotype and optimal design to fully consider processing technology and the requirement of structure cost, obtained a simple structure's phone lens battery of lens. This product reasonable in design, the practicality is strong, has better 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.
Embodiment
