Workers working at high altitudes now often burn some welding gas, but because of the irritating white light during the firing process, this is very harmful to the eyes and will cause various eye diseases over time.

The sapphire protective film is also called the sapphire protective window. It is a special window used to protect the observer, the inside of the instrument and the inside of the container by using the pressure, abrasion, and high temperature characteristics of sapphire. It has ultra-high surface hardness and chemical resistance, can transmit wavelengths from UV to mid-infrared, and is thinner and stronger than standard glass windows.
