Description

Optical lens piece coating film anchor clamps with radian

Technical Field

The utility model relates to an optical lens piece processing technology field, in particular to optical lens piece coating fixture with radian.

Background

The optical coating refers to a process of coating one or more layers of metal or dielectric films on the surface of an optical part. The purpose of coating the surface of the optical component is to increase the requirements of light reflection, beam splitting, color separation, light filtering and the like. In actual operation, modern coating fixtures are basically horizontal, and a partially processed workpiece disc is a spherical surface with radian, so that only the middle area of the fixture can be on the same spherical surface with the spherical surface of the hole disc, and other four corners are higher than the spherical surface of the hole disc. The fixture is matched with the arc-shaped spherical surface to generate the phenomenon of uneven coating, and the whole fixture and a product piece can shake along with the mechanical rotation of a workpiece disc in the coating process. Only because the normal coating index requirement is not too strict, the uniformity difference of the indexes of the products coated on the same fixture has little influence on the product indexes, and the product indexes are all in a qualified range, the coating of the common products is not greatly influenced. However, for the optical filter which needs to be cut into small pieces after being coated, the optical filter has small index allowance and all area indexes of the product need to be guaranteed to be qualified, so that the edge and corner of the horizontal clamp are not positioned on the spherical surface of the hole plate, and the coating effect of the final finished product is affected.

Therefore, further improvements are needed to address the above problems with the prior art.
