Abstract
The utility model relates to a non-spherical surface lens used for mobile phones. The utility model comprises a first non-spherical surface and a second non-spherical surface, an anti-reflective film layer is coated on the first non-spherical surface and the second non-spherical surface, the anti-reflective film layer comprises a membranous layer with high refractive index, and a membranous layer with a low refractive index covered outside the layer of the high index of refraction. The anti-reflective film layer is coated on the utility model, to ensure that the reflection loss of the incoming ray of the object space is reduced, and more optical lines can participate in the imaging; and the application of the non-spherical surface lens can guarantees the photography device of the whole portable type communication terminal to maintain the small volume, and simultaneously to have good optical performance.
Description
Technical field
The utility model relates to a kind of mobile phone aspheric lens.
Background technology
Nowadays, in order to cater to consumer's needs, be equipped with camera head on the increasing mobile phone, make the user to note down easily oneself to want the image of taking whenever and wherever possible.With typical CCD camera different with video camera be that the optical lens that is equipped with on the mobile phone is subjected to the qualification of handset size. can only use size camera lens little, in light weight, simple in structure.
The eyeglass that is adopted in traditional optical lens mostly is spherical mirror, and its lens face is the part of sphere, relatively easy processing, however the use of spherical mirror can bring multiple aberrations such as spherical aberration again, causes the distortion distortion (as shown in Figure 1) of imaging.In order to proofread and correct these aberrations, can in imaging system, use lens combination, by multi-disc curvature, the combination of positive and negative different spherical lens, offset or reduce the part aberration, make imaging effect better.And for the portable communication terminals such as mobile phone that size restrictions is arranged, installing a complex set of lens combination thereon is be difficult to row logical, so mobile phone manufacturer has turned to aspheric mirror to sight one after another.Aspheric mirror, as its name suggests, the plane of refraction of its lens and aspheric surface, its use can be eliminated the intrinsic aberration of a lot of spherical mirrors (as shown in Figure 2), and can improve image planes and distort aberration, the rectification ability of one piece aspheric mirror equals many pieces of spheric glasses, so the use aspherical lens can be in the light-weighted optical property preferably that guarantees simultaneously in the camera lens.
Summary of the invention
The utility model purpose provides a kind of mobile phone aspheric lens, is coated with antireflection film layer on it, makes the reflection loss of object space incident ray reduce, and more rays is participated in imaging; And the application of aspherical lens can be so that the camera head of whole portable communication terminal also has the good optical performance when keeping small and exquisite volume.
The technical solution of the utility model is: a kind of mobile phone aspheric lens, comprise first aspheric surface and second aspheric surface, be coated with antireflection film layer on described first aspheric surface and second aspheric surface, described antireflection film layer includes two-layer, near the high refractive index layer of sphere, and the outer low-index film that coats of high refractive index layer.
The further technical scheme of the utility model is: a kind of mobile phone aspheric lens, comprise first aspheric surface and second aspheric surface, be coated with antireflection film layer on described first aspheric surface and second aspheric surface, described antireflection film layer includes two-layer, near the high refractive index layer of sphere, and the outer low-index film that coats of high refractive index layer; Described high refractive index layer is the titania material, and described low-index film is the silicon dioxide material.
The utility model advantage is:
1. be coated with antireflection film layer on the utility model, make the reflection loss of object space incident ray reduce, more rays is participated in imaging, the brightness of image height, and quality is good.
2. application of the present utility model can be so that the camera head of whole portable communication terminal also has the good optical performance when keeping small and exquisite volume.

Fig. 2 passes through aspheric mirror imaging synoptic diagram for light;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the utility model partial sectional view.
Wherein: 1 first aspheric surface; 2 second aspheric surfaces; 3 antireflection film layers; 31 high refractive index layers; 32 low-index films.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 3, Figure 4, a kind of mobile phone aspheric lens, comprise first aspheric surface 1 and second aspheric surface 2, be coated with antireflection film layer 3 on described first aspheric surface 1 and second aspheric surface 2, described antireflection film layer 3 includes two-layer, near the high refractive index layer 31 of sphere, and the high refractive index layer 31 outer low-index films 32 that coat.Described high refractive index layer 31 is the titania material, and described low-index film 32 is the silicon dioxide material.
Be coated with antireflection film layer on the utility model, make the reflection loss of object space incident ray reduce, more rays is participated in imaging; And the application of aspherical lens can be so that the camera head of whole portable communication terminal also has the good optical performance when keeping small and exquisite volume.
