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.
Application
Sapphire is widely used in the medical and beauty machinery
industry. I believe everyone has heard of the hair removal
instrument. I believe many girls have also used hair removal cream,
hair removal device, etc. as for the hair removal instrument, many
