Technology for preparing lens through physical vapor deposition

Abstract

The invention relates to a technology for preparing a lens through physical vapor deposition. The implement mode of the technology comprises the steps that a pattern covering film is firstly prepared,then metal or glass or plastic is selected as a base material, a back pattern is stamped or cast, then polishing, grinding, cleaning and drying are performed in sequence, then physical vapor deposition such as vacuum evaporation or magnetron sputtering is performed to obtain a reflection film, a pattern film is obtained through plating, a first surface protective film is obtained through plating,a second surface protective film is obtained through plating, and finally, a lens surface with the back pattern to be shown in reflection light is prepared. According to the technology, an ancient lens technology and a modern thin film technology are combined, the preparing process saves energy and is environmentally friendly, the light-transmitting pattern is clear and resistant to abrasion andcorrosion, the mystique of the ancient technology is reserved while modern scientific and technological elements are added, and combination of the sun culture and technologies are perfectly displayed.

Description

(1) Technical field [0001] The invention relates to a process for manufacturing a light-transmitting mirror, in particular to a process for preparing a light-transmitting mirror by physical vapor deposition. (2) Technical background [0002] The mechanism that the light-transmitting mirror can reflect the pattern on the back of the mirror has been explained in Shen Kuo's "Mengxi Bi Tan", that is, the sand casting process is used to cast a pattern on the back of the mirror, and the front is polished after the casting is cooled. When the mirror is thin enough, the mirror surface will reveal the graphics on the back in the reflection. This process is laborious and time-consuming, and it is not economical. At present, some domestic manufacturers use rough polishing of the mirror surface first, then use machinery or laser to engrave the image on the back of the mirror surface, and then polish the mirror surface finely, so that the traces of the pattern are not easy to see with th...

Problems solved by technology

[0003] The purpose of the present invention is to provide a process for preparing light-transmitting mirrors by physical vapor deposition, which solves the rough manufacturing process of ancient light-transmitting mirrors, which is labor-intensive, time-consuming, and uneconomical; The manufacturing traces can be seen, and the edge of the reflected image is not clear. In addition, it also solves the limitation that the light-transmitting mirror can only be made of metal materials.
