Chemically, sapphire is single crystal aluminum oxide
(Al2O3), and is useful in a transmission range from 0.2 -
5.5µm.Sapphire , so making them ideal materials for demanding
applications (such as laser systems) because of their extreme
surface hardness, high thermal conductivity, high dielectric
constant and resistance to common chemical acids and alkalis. And
sapphire also is the second hardest crystal next to diamonds
and, because of their structural strength, sapphire windows can be
made much thinner than other common dielectric windows with
improved transmittance.
