epi-ready,sapphire thick glass lens for covering,sapphire optical
windows,2inch 0.1mm thickness sapphire wafer,
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.-------------------------------------------------------------------------------------
We can supply professional customized service in time and provide
cooperation and support of new product development and technology
appliance.
