A sapphire window is a window made using durable sapphire glass.
Due to its properties of hardness, heat resistance, and chemical resistance, it finds applications in various fields. The operating principle is similar to that of a regular window, where sapphire glass allows light to pass through and admits external light.
Utilized in medical devices, industrial equipment, high-end watches, and more, the basic structure of a sapphire window consists of sapphire glass and its fixing frame. The distinctive features of sapphire windows include extremely high hardness (Mohs hardness of 9), heat resistance (approximately 2000°C), chemical resistance, and transparency. Points to note when using them include avoiding strong impacts, high temperatures, and exposure to chemical substances.
