Small Sapphire Crystal Single Cylinder Watch Glass

Why Choose sapphire crystal?

Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm

Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond.

Because of its hardness (second only to Diamond), Sapphires are used in industrial applications such as components for watch crystals and movement bearings, scientific instruments, high-durability windows, and insulating substrates in special purpose solid state electronics

Sapphire is grown using a variety of methods. Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method.

Sapphire is able to be cut thinner than alternative crystals due to its structural durability.

Sapphire crystals features:

1#Thinner and Stronger than Standard Glass Windows 

2#Transmits Wavelengths Ranging From UV to Mid-Infrared

 3#Features Extreme Surface Hardness and Chemical Resistance
