Sapphire  Crystal

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 visible to the near infrared is required.

Maximum available size for windows, lenses and blanks: 100 mm Dia x 10 mm Thk and 100 mm Square x 10 mm Thk. Sapphire is also available in form of round rod (2-20 mm Dia, 150-300 mm long), rectangular and square rod and ribbon (10-80 mm wide, 1-4 mm thick, 150-300 mm long), tubing (3-30 mm Dia, 1-8 mm wall thickness, 150-300 mm long) and other custom cross-section configurations.
