Description

A lens coating assembly line process

Technical field

The present invention relates to the technical field of lens coating, and specifically to a lens coating assembly line process.

Background technique

Lens coating is a technology that adds one or more layers of film to the surface of the lens to improve the optical performance of the lens and protect the lens. The purpose of the coating is to reduce reflected light, increase light transmittance, enhance anti-reflection capabilities, and improve color reproduction. Degree, etc., the quality of the coating directly affects the imaging quality and service life of the lens. Therefore, in the lens manufacturing process, advanced equipment and processes need to be used to ensure the quality and stability of the coating.

In order to avoid the impact of impurities and pollutants in the air on the coating effect, during the coating process, a vacuum pump is often used to create and maintain the necessary vacuum environment, thereby improving the uniformity and quality of the coating. This results in the lens entering and exiting the coating When operating the coating machine, you need to open and close the cover of the coating machine to ensure the airtightness of the internal environment. At the same time, in order to further improve the optical performance, anti-reflection capability and protective layer quality of the lens, another set of coating equipment with different coating parameters will be used to perform secondary coating on the lens, which not only increases the investment cost but also extends the coating time.

In view of this, we propose a lens coating assembly line process.
