- Product description
- Parameter
"SLTC is professional in steadily supplying various large size crystal bars, windows and other products in Sapphire, which is available in ultraviolet, visible light and middle infrared fields at the same time. Therefore, it is treated as one of the most ideal optical windows and protective windows of optical lenses, widely applied in aerospace and medical equipment.
SLTC has won words of mouth in producing different flat windows in sapphire, Zns and other optical materials. Now SLTC has already introduced some core equipment and made some breakthroughs in producing high precise large flat windows, the largest size we could reach is 600 X 600, surface precise is up to RMS: 1/60λ, parallel error is less than 1″and the surface quality is higher than 20-10. In aerial photography, optical imaging etc. it serves as an observation windows, high powered laser windows, infrared optical windows widely being made use of.-
