Description

technical field

[0001] The invention relates to the technical field of optical coating, in particular to a coating jig. Background technique

[0002] With the development of the optical industry, more and more types of products need to be coated to obtain specific optical properties. For the coating of optical lenses, vacuum coating equipment is usually used in the industry for evaporation coating to complete the deposition of film layers on the surface of the substrate.

[0003] Vacuum coating equipment is generally a large-scale machine chamber, and the large-scale coating fixtures usually used are umbrella-shaped. Coated products need to be loaded with a jig and placed on the fan-shaped plate of the coating machine for coating. The evaporated molecules of the vacuum coating film material move along a straight line, and the different curvature lenses, aspheric lenses and different areas have different evaporation incident angles, resulting in a large difference in the fi...
