Fire alarm monitoring protective glass

Fire alarm monitoring protection glass sapphire window panel

Uncoated sapphire has excellent surface hardness and a transmittance range extending from ultraviolet to mid infrared wavelengths. Sapphire can only be scratched by a few substances other than it. Uncoated substrates have chemical inertness and are insoluble in water, common acids, or bases at temperatures up to approximately 1000 ° C.

Sapphire is resistant to high temperatures, has good thermal conductivity, high hardness, is transparent to ultraviolet and infrared radiation, and has good chemical stability. Widely used in multiple fields such as industry, national defense, and scientific research (such as high-temperature resistant infrared windows).
