Sapphire Windows manufactured from single crystal
sapphire are ideal for demanding applications such as laser systems, where high
pressures, high temperatures, high thermal loads, vacuum conditions,
scratch/wear resistance, low friction and corrosive atmospheres are important
considerations. As a result, they are
often used in research, medical, aerospace and military applications. Here are some reasons why.
- Except for diamonds, sapphire is the hardest crystal known to man. On the Mohs scale of hardness, which ranks materials from softest (1) to hardest (10), it is rated 9.
- Because of its structural strength, sapphire optical windows can be made much thinner than other common dielectric optical windows with improved transmittance as a result.
- Sapphire opticalwindows have a very wide optical transmission band from UV to near-IR (0.15-5.5µm). Because of their high transmittance from 150 nm to 5 µm, they are much preferred in aerospace applications.
Because of Sapphire outstanding physical, chemical and
optical properties, sapphire wave plates are often used in the most demanding
military and aerospace applications.
