Photosensitive paint is a kind of paint with photosensitive properties. The color will change when exposed to the sun's ultraviolet rays, and will return to the original color when the sun/ultraviolet rays are lost.
This article is the coating experiment of photosensitive paint on the lens made by the technical engineers of NBCHAO. The substrate is glass lens, and the paint is photosensitive glue. The effect of the coating film is checked by scraping on the experimental automatic film coating machine.
Special reminder: The experiment should be carried out in an environment that avoids sunlight, and the lens must be free of any impurities, otherwise it may cause scratches on the coating. affect the coating effect.
Below is the lab demo video.
Note: The darker color at the top of the film on the video is mainly due to the amount of photosensitive paint placed on the top, and the overall film effect is relatively uniform.
