Embodiment

[0030] An embodiment of the present invention provides a processing method for an optical lens complex, including the following processing flow:

[0031] S1 Primary processing of raw materials

[0032] Cut the original material of the optical lens and the original material of the polarizer into discs of the same size, and fix the two discs in the grinding device to first grind the concave-convex surface, and make the concave-convex surface concentric with the center of the sphere. The edge of the raw material is ground to make the edge polished to a cylindrical shape, and the diameters of the cylindrical surfaces of the two raw materials are the same, and the curvatures of the corresponding surfaces of the two raw materials after the initial processing are the same, which is convenient for the subsequent compounding process;

[0033] S2 fine grinding

[0034] Use 5000 mesh, 8000 mesh, and 10000 mesh water sandpaper to polish the concave-convex surface of the two kinds of wafe...

Abstract

The invention provides a processing method of an optical lens complex, and relates to the field of optical lens processing. The processing method of the optical lens complex comprises the following processing flows: S1, primary processing of raw materials; S2, accurate grinding processing; S3, ultrasonic cleaning; S4, vacuum coating of an antireflection film; S5, composite treatment; S6, cylindrical surface repairing; and S7, vacuum coating of a sapphire film. An optical lens wafer and a polarizer wafer are subjected to high-precision polishing before compounding, and then the antireflection film is plated, so that the influence on light transmittance after compounding can be ensured, optical adhesive bonding is performed in a heated environment, then clamping and heating are performed, air between gaps can be effectively exhausted, the abrasion resistance of the product can be improved through coating the sapphire film, the product is not prone to abrasion, and then the service life of the product is guaranteed.

Description

technical field [0001] The invention relates to the field of optical lens processing, in particular to a processing method for an optical lens complex. Background technique [0002] Optical lenses are an important part of various optical instruments, cameras, and lenses. Since sunlight contains a variety of rays that affect the use of optical instruments and cameras, polarizers are used to block them to soften the light. When composite materials and optical lens raw materials are combined into an optical lens composite, the polishing accuracy and the bonding of the optical lens composite will affect the quality of the optical lens composite product. , camera, lens life. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a processing method of the optical lens complex, which solves the problems that the interstitial air will affect the quality and the wear resistance of the ...
