Why Choose sapphire crystal?

A synthetic sapphire crystal or “glass” is actually not glass at all. It is a very hard, transparent material made of crystallizing pure aluminum oxide at very high temperatures. Synthetic sapphire has the same hardness as natural sapphire gemstones, but without the colouring agents that give the gems their various hues
Sapphire (Al2O3) is a superior optical material which is used for its excellent optical, chemical and physical properties for use in the UV, Visible and Infra-red regions. Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond. Sapphire is able to be cut thinner than alternative crystals due to its structural durability.

Optical crystals are used as view ports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical crystals are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire crystal has several unique properties that make it the ideal material for these applications.
