0.005mm Sapphire Optical Window Plano Convex Lens

Sapphire Spherical Lens Planoconvex Lens Flat Concave Lens Optial Window

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.

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 of them are made of sapphire. It can be said that it is an industrial product, not a personal product. Many people will encounter this instrument when they go to beauty treatment; Compared with the traditional depilator, it can improve the personal problems such as rough skin surface, large pores and dark complexion, make the skin white, uniform and elastic, remove red blood, restore good complexion, and make the skin tender and smooth as snow; For acne, in the scientific beauty therapy industry, there is no need to use a knife for surgery. Using this technology, it can remove pain painlessly and alleviate pain; At present, most hair removal instruments are sapphire three in one hair removal instruments with fine quality. It can be said to be a laser hair removal technology, which is convenient to use. Its flat cold bald head can make users feel cold, comfortable and painless in the process of use. They can be used by themselves after buying. If they are too troublesome, they can go directly to medical institutions. The price is not expensive, and they have a sense of experience.

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.
