Aerospace: Because of its perfect durability and corrosion resistance, high temperature resistance, but also a very wide range of spectral transmission, sapphire windows are widely used in aerospace equipment and instruments.
Sapphire flash lamps: Sapphire’s high temperature resistance and low thermal expansion rate make it a protective window for high-strength lamps as well as flash lights. Scratch resistant, no burst.
Applications of analytical instruments: In many analytical cases, the gas or liquid analysed is highly corrosive. The sapphire window is perfectly corrosion-resistant and is widely used in such analytical instruments. In addition, sapphire window has a good transmittance from ultraviolet to infrared wide spectrum, which makes it more widely used in spectral range.
Applications of medical equipments: Due to its excellent durability, sapphire windows are widely used in a variety of medical applications such as laser medical instruments, laser beauty instruments and endoscopes.
Optical applications: Because of the wide spectral range of sapphire crystals, sapphire windows can be used in all kinds of optical applications, from ultraviolet to infrared. In terms of mechanical and physical properties, it has an advantage over the optical windows of other materials.
Illumination applications: Sapphire window has a good heat resistance, for very high brightness lighting, it is a good protection window material.
Watchs and industry instruments: Sapphire windows are considered to be protective covers for watches or gauges and are resistant to scratches, robustness and non-bursting.
