Sapphire windows description:

Sapphire has a wide transmission range, spanning the three wavelength bands of ultraviolet, visible light and infrared and has high thermal shock resistance, high hardness and wear resistance. Almost no substance except the diamond can produce scratches on its surface, and its chemical properties are stable which is insoluble in most acid solutions. Furthermore, because of its high strength, windows made of sapphire are thinner.

Different Types of Sapphire Windows

Sapphire has better light transmittance in the wavelength range of 0.20 - 5.50 μm and the infrared transmittance hardly changes with temperature.

Square and rectangle sapphire windows are widely used in many fields, such as high-temperature infrared windows, bar code scanning windows and various optical components.

Due to the extensive applications of sapphire in various fields, different dimensions are required. Stanford Advanced Materials can provide custom sapphire windows of any size and thickness in complete orientations.
