The optical windows are used to separate the environment on both sides, such as separating the inside and outside of the instrument, so that the inside and outside of the instrument are isolated from each other, thereby protecting the internal devices. The window is the basic optical element, an optical flat plate that does not change the optical magnification and only affects the optical path in the optical path. The important parameters of the window are: light transmittance, surface accuracy, thickness, parallelism, substrate material and other attributes. The window with suitable parameters can be selected according to the specific application.
Sapphire is a hard crystal,it widely been used for watch and mobilephone, Beauty equipment ,lasers,LED, and so on.
1. Why choose the sapphire?
Thinner and Stronger than Standard Glass Windows
Transmits Wavelengths Ranging From UV to Mid-Infrared
Features Extreme Surface Hardness and Chemical Resistance
2. What is sapphire windows
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.
