PriceList for Silver Coated Quartz Triple Bore - 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.

Product Characteristics

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.
