Sapphire

Sapphire is a 'water white' or clear synthetic optical material consisting of single crystal Al₂O₃.  There are several methods of growth including flame fusion, edge defined film growth, Czochralski and HEM (Heat Exchange Method).

Sapphire is transparent from around 180 nm in the ultraviolet to around 6 microns in the IR.  Exact transmittance is a function of thickness and purity.  Sapphire is a very hard material so is difficult and expensive to cut, grind and polish.   Sapphire melts at a very high temperature so it is expensive to grow.

We specialize in supply of  large (larger than 10 cm diameter)  sapphire shapes and windows, which we export, principally to the Pacific Rim.
