Pressure resistant sapphire window glass

Sapphire pressure protection window piece is a plane polishing product based on the processing of single crystal sapphire. Sapphire pressure protection window piece is a special window piece used to protect the observer, the inside of the instrument and the inside of the container by using the characteristics of sapphire pressure resistance, wear resistance and high temperature resistance.

Single crystal sapphire window sheets Feichang are suitable for demanding applications (such as laser systems) because of their excellent surface hardness, high thermal conductivity, high permittivity, and resistance to chemical acids and bases. Since the hardness of sapphire is second only to diamond and its structural strength is feichang high, the thickness of sapphire window pieces made by adding enhanced light transmission is thinner than that of normal high dielectric window pieces. In terms of chemistry, sapphire is single crystal aluminum trioxide (Al2O3). Feichang is suitable for transmission between 0.2zhi5.5μm. In general optical applications, the basic needs of customers can be met without coating treatment. Our products can also be coated according to customer needs, screen printing or special heat treatment, to meet the special needs of customers.

With ultra-high surface hardness and chemical resistance;

1, transmittable UVzhi between the wavelength of infrared;

2, thinner and stronger than the standard glass window sheet.

3, the product shape is divided into: round, rectangular, step shape and all kinds of machining shape.

4, product size range: diameter (large diagonal)10-500mm, thickness 0.3-100mm.

5, product finish after polishing: 80/50, 60/40, 40/20, 20/10, 10/5 optional (American Army standard).

6, surface flatness (surface type) : up to 1/10λ.

7, pressure resistant sapphire window glass applicable occasions: high pressure reaction kettle, deep water, geological rock exploration, chemical industry, vacuum vessel and so on.

8, under the same pressure conditions, the thickness of pressure resistant sapphire window glass can be thin Zhi 1/5 of tempered glass.
