Product description

Single crystal sapphire possesses a unique combination of excellent optical, physical and chemical properties. The 

hardest of the oxide crystals, sapphire retains its high strength at high temperatures, has good thermal properties and 

excellent transparency. It is chemically resistant to common acids and alkali at temperatures up to 1000 °C as well as to 

HF below 300 °C . These properties encourage its wide use in hostile environments where optical transmission in the range 

from the vacuum ultraviolet to the near infrared is required. Sapphire is anisotropic hexagonal crystal. Its properties depend 

on crystallographic direction (relative to the optical C-axis).

 Note for Sapphire Window:

(1). Custom-made Sapphire windows at any size are available.

Besides round, Sapphire windows at shape of quadrate, triangular, or other polygonal are available

(2). Other thickness from 0.5mm to 50.0 mm is available upon request.

(3). Better bevel is available upon request.

(4). Windows with Anti-Reflective(AR).
