Sapphire Windows
Product Information :
Sapphire material has high hardness (Moths 9) so it’s very scratch resistant, has high melting point (2050 °C) and good thermal stability, sapphire is also corrosion-resistant and has a high transmission rate in the infrared spectrum. Thusly sapphire is the best window material for Hi-Power lasers, mid and multi-spectrum range. Utilization in satellite control panel monitors, sensor system on fire control, thermal and shaking environmental testing, and aerospace technologies is common.
