We constantly think and practice corresponding to the change of circumstance, and grow up. We aim at the achievement of a richer mind and body along with the living for Fused Silicon Wafer Carrier, Fused Quartz Substrates, Ptfe Laser Diffuse Reflectors, Since the manufacturing facility founded, we have now committed on the progress of new products. While using the social and economic pace, we are going to continue to carry forward the spirit of "high high-quality, efficiency, innovation, integrity", and persist with the operating principle of "credit to start with, customer initially, top quality excellent". We'll make a amazing long run in hair output with our companions.
Factory best selling Laser Cavity Reflector - Sapphire Optical Windows – LZY Detail:

Uncoated sapphire has excellent surface hardness, and the range of transmittance extends from ultraviolet to mid-infrared wavelength region. Sapphire can only be scratched by a few substances other than it. The uncoated substrate is chemically inert and insoluble in water, common acids or alkalis at temperatures up to about 1000°C. Our sapphire window is a z-axis section, so the c-axis of the crystal is parallel to the optical axis, eliminating the birefringence effect of transmitted light.

Material Properties

Sapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. It is often used as window materials in specific field such as space technology where scratch or high temperature resistance is required.
