Sapphire has better light transmittance in the wavelength range of 0.20 - 5.50 μm and the infrared transmittance hardly changes with temperature. The sapphire window's transmittance CRYSCORE manufactures is higher than 85 % at 380 nm to 780 nm.
The sapphire windows with round shape produce by CRYSCORE have a series of excellent characteristics, such as high strength and hardness, the high-temperature resistance abrasives, good corrosion resistance ability, excellent light penetrability, and electric insulation performance. The maximum diameter we supply is up to dia. 290 mm.
