Dia 2inch Synthetic Sapphire Rod
Properties of Sapphire Rod
Optical Windows are used as viewports to protect other components
within an optical assembly, instrument, or laser. In certain
applications, optical windows are required to withstand harsh
environmental conditions and provide high levels of performance and
reliability. Sapphire window has several unique properties that
make it the ideal material for these applications.
Description
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
