Abstract
The invention discloses a device for eliminating VR dispersion and distortion. The device is a combination lens with the use of a concave lens and a convex lens. The convex surface of the convex lens and the concave surface of the concave lens are arranged in a matched way. Both the concave lens and the convex lens are made of a resin material and have different refractive indexes and Abbe numbers, the refractive indexes of the convex lens and the concave lens are 1.4 to 1.6, the Abbe numbers are 25 to 65, the refractive index of the convex lens is low, the Abbe number of the convex lens is high, the refractive index of the concave lens is high, and the Abbe number of the concave lens is low. According to the combination lens, chromatic aberration is eliminated through distributing different optical powers, spherical aberration is eliminated through a method of changing each curved surface curvature, distortion is eliminated through changing each curved surface curvature, and coma is eliminated through changing different resin materials of the lenses. The combination lens of the invention is made of the resin material and can be formed by injection molding, and the combination lens has the advantages of convenience in processing, clear imaging, small distortion, a small color difference, high cost performance, a compact structure and is consistent with the development requirement of a VR integrated machine.
Description
Technical field
The present invention relates to VR machine technical field, a kind of device eliminating VR dispersion and distortion.
Background technology
VR all-in-one is the head-mounted display apparatus possessing independent processor.The function having possessed operation independent, having inputted and export.
Owing to same transparent medium exists the difference of refractive index to the light of different wave length, and therefore white light is made up of the white light of different wave length, and transparency material can occur dispersion when reflecting white light, distort this phenomenon.Accordingly, it would be desirable to design a kind of method eliminating VR dispersion and distortion, meet the manufacture claim of VR all-in-one.
Summary of the invention
It is an object of the invention to provide a kind of device eliminating VR dispersion and distortion, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
A kind of device eliminating VR dispersion and distortion, described device is a compound lens, described compound lens uses convex lens and concavees lens, the convex surface of described convex lens is equipped with the concave surface of concavees lens, described convex lens and concavees lens all use resin material, having different refractive indexs and Abbe number, the refractive index of described convex lens and concavees lens is 1.4-1.6, Abbe number 25-65.
As the further scheme of the present invention: described compound lens is by distributing different focal power achromatisms.
As the present invention further scheme: described compound lens is by changing the method aplanasia of each curvature of curved surface.
As the present invention further scheme: described compound lens is disappeared distortion by the method changing each curvature of curved surface.
As the present invention further scheme: described compound lens eliminates coma by changing the different resin material of lens.
Compared with prior art, the invention has the beneficial effects as follows: compound lens uses resin material, can injection mo(u)lding, it is simple to processing；Imaging clearly；Distorting little, aberration is little, high performance-price ratio, compact conformation, meets the manufacture claim of VR all-in-one.
Accompanying drawing explanation
Fig. 1 is the structural representation eliminating VR dispersion with the device of distortion.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of device eliminating VR dispersion and distortion, described device is a compound lens, described compound lens uses convex lens 1 and concavees lens 2, the convex surface of described convex lens 1 is equipped with the concave surface of concavees lens 2, described convex lens 1 and concavees lens 2 all use resin material, having different refractive indexs and Abbe number, convex lens refractive index is low, and Abbe number is high, concavees lens refractive index is high, Abbe number is low, and the refractive index of described convex lens and concavees lens is 1.4-1.6, Abbe number 25-65.
The focal power method achromatism that described compound lens is suitable for by distribution, by changing method aplanasia and the distortion of each curvature of curved surface, eliminates coma by changing the different resin material of lens.
Further, in the present embodiment, described compound lens is by distributing different focal power achromatisms.
In the present embodiment, calculate different curvature of curved surface by optical software.
The compound lens of the present invention uses resin material, can injection mo(u)lding, it is simple to processing；Imaging clearly；Distorting little, aberration is little, high performance-price ratio, compact conformation, meets the manufacture claim of VR all-in-one.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
