Three Hole Spherical Glass Cavity For High-power Laser
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.
According to the application, we have following materials available to choose:
● Fused Quartz
● Synthetic Silica Glass
● Borosilicate glass
● Cerium doped quartz
● Spherical Glass
● Samarium doped glass
