Description

Technical Field

[0001] This utility model belongs to the field of lens coating technology, specifically a coating device for optical lenses. Background Technology

[0002] Coating is a process of applying a transparent electrolyte or metal film to the surface of an optical lens using physical or chemical methods. The purpose is to change the reflection and transmission characteristics of the lens surface and control the reflectivity and transmittance of the substrate to the incident light beam in order to meet different needs.

[0003] Currently, optical lenses are coated using liquid immersion coating. During the process of immersing the suspended lens in varnish (hardening liquid), the repeated lifting and lowering of the container causes fluctuations in the varnish (hardening liquid) inside. Due to the different viscosities of the varnish (hardening liquid), the fluctuating varnish (hardening liquid) will cause a wavy cured layer to appear on the lens surface, affecting the lens's performance.

[0005] Therefore, this utility model provides a coating device for optical lenses. Utility Model Content
