The product shall be manufactured from high quality optical grade Czochralski grown color sapphire crystals.

They are widely applied in luxury watches and the dimensions could be customized.

Sapphire has very stable chemical properties and is not corroded by acid and alkali. The hardness of sapphire is very high, with Mohs hardness of 9, second only to the hardest diamond. It has good light transmittance, thermal conductivity, electrical insulation, good mechanical properties, wear resistance and wind erosion resistance. The maximum operating temperature is 1900 ℃.

Because the high-quality artificial sapphire crystal material has good light transmittance in the wave band of 170nm ~ 6000nm, and the infrared transmittance hardly changes with temperature, the optical elements and infrared transparent optical windows made of high-quality artificial sapphire are widely used in military night vision infrared transparent equipment, low-temperature laboratory observation port High precision instruments and meters for navigation, aerospace and aviation have been fully applied.
