Abstract

The utility model discloses a mobile phone lens, comprising a lens cone and a base which are matched with each other. The mobile phone lens is characterized in that a first plastic lens and a second plastic lens are laminated in the lens cone, the first plastic lens and the second plastic lens are provided with a space ring therebetween, and meanwhile, the second plastic lens is provided with a dispensing layer at the position where the second plastic lens is contacted with the inner wall of the lens cone. According to the scheme disclosed by the utility model, a purpose of reducing the lens size is achieved, thereby being adapt to a market requirement of miniaturization, and having very high practical values and popularization values.

Description

A kind of mobile lens

Technical field

The utility model relates to a kind of optical lens, specifically, relates to a kind of mobile lens.

Background technology

Along with popularizing of mobile phone, its function is also more and more abundanter, and the combination of mobile phone and camera has brought a quantum leap to cell-phone function.On mobile phone, realizing the function of camera, be mainly that camera lens is installed on mobile phone, and mobile phone volume is little, correspondingly also just requires the camera lens volume that is arranged on mobile phone also the smaller the better, only in this way, could adapt to the social demand of miniaturization of electronic products.

Utility model content

The purpose of this utility model is to provide a kind of mobile lens, by the improvement to structure, its volume is reduced to greatest extent.

To achieve these goals, the technical solution adopted in the utility model is as follows:

A kind of mobile lens, comprise the lens barrel and the base that cooperatively interact, it is characterized in that, in described lens barrel inner stacks, there are the first plastic lens and the second plastic lens, between this first plastic lens and the second plastic lens, be provided with spacer ring, meanwhile, the position that described the second plastic lens contacts with lens barrel inwall arranges a glue-line.Described lens barrel is plastic cement lens barrel; Described base is plastic base.

Further, described the first plastic lens is convex lens; Described the second plastic lens is concavees lens.

Further, on described base madial wall, be provided with internal thread, on the lateral wall of described lens barrel, be provided with the external thread matching with this internal thread.

Compared with prior art, the utlity model has following beneficial effect:

(1) the utility model, by two eyeglasses are set in lens barrel, is realized the basic function of mobile lens, and its gross thickness reduces greatly; And two eyeglasses are directly fixed on lens barrel inside by gluing process, not only production and processing is simple, and safe and reliable.

(2) the utility model is simple in structure, and it is convenient to realize, more existing mobile lens, and its thickness reduces greatly, has adapted to the demand of mobile phone to camera lens miniaturization.

(3) in the utility model, all parts are all made by plastic cement, not only lightweight, and good toughness, durable in use.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.

Embodiment

As shown in Fig. 1～Fig. 6, the disclosed mobile lens of the utility model, mainly comprises lens barrel 1, base 2, the first plastic lens 3 and the second plastic lens 4.Described lens barrel 1 integral body is cylindric, and one offers light hole on a bottom surface, and described the first plastic lens 3 is arranged on the position near this light hole, and first center of plastic lens 3 and the center-aligned of this light hole.The second plastic lens 4 is arranged on lens barrel inside near the first plastic lens 3, and both are mutually stacked, at the edge of the second plastic lens, the position contacting with described lens barrel inwall, utilize gluing process, set-point glue-line 6, is fixed on the second plastic lens on lens barrel inwall.Because the second plastic lens and the first plastic lens are stacked relation, and mutually near, therefore, after the second plastic lens is fixed, the first plastic lens has also been fixed.

In order to realize better the utility model, between the first plastic lens 3 and the second plastic lens 4, spacer ring 5 is installed.

For the ease of installing and using, on the lateral wall of described lens barrel, be provided with external thread, on the madial wall of described base, be provided with internal thread, described lens barrel and base are assembled and are used by cooperatively interacting of external thread and internal thread.

In order to improve better effect, the utility model has carried out delustring processing to parts such as lens barrel, the second plastic lens.

In the present embodiment, the effective path length of the light of the first plastic lens is 0.55～0.61; Centre wavelength: Ravg%<0.5, Rmax%<1at420～680nm; Optics is eccentric: the eccentric <3 μ of one side m, meets personally eccentric <3 μ m; Surface figure accuracy≤1 μ m; Surfaceness <0.01 μ.The light effective diameter of the second plastic lens is 0.74～1.27, centre wavelength: Ravg%<0.5, Rmax%<1at420～680nm; Optics is eccentric: the eccentric <3 μ of one side m, meets personally eccentric <3 μ m; Surface figure accuracy≤1 μ m; Surfaceness <0.01 μ.

By check, the mobile lens that the utility model provides, its performance parameter is as follows:

EFL：1.33

F／NO：2.8

TTL：1.74MM

Max?Image?Size：2.1MM(FOV?D=74°)

FOV(V／H／D)：43.6°／55.8°／67.5°

TV-DISTORTION<1.5％

RELATIVE?LLLUMINANCE>50％

CHIEF?RAY?ANGLE<32.5°

FOCAL?RANGE：20CM～∞

Wherein, concrete lens parameters is as following table:

As can be seen here, the utility model is not only simple in structure, easy to use, and volume is little, cost is low, superior performance, has very high practical value.

Above-described embodiment is only preferred embodiment of the present utility model; the not restriction to the utility model protection domain; in every case adopt design concept of the present utility model, and carry out non-creativeness work on this basis and the variation made, within all should belonging to protection domain of the present utility model.
