Projector glass

With quality float 3.3 borosilicate glass sheet, Professional cutting, grinding, special process of tempering heat treatment processing, ensure borosilicate glass surface and internal quality, light transmittance up to 90%. For long time working temperature of 450 °C, thermal shock of 270°C.

Borosilicate AR coating use the international leading chemical coating process: sol-gel method. The coating and glass plate make up as a lasting chemical bonding which can be tempered to last as long as the glass itself. The coating is tough withstand wind, sun, rain and frost. Float borosilicate glass with AR coating reach transmittance up to 97 percent, better than physical coating process such as magnetron sputtering.
