Circular sapphire windows are circular-shaped optical components made from sapphire, which is a high-performance material with excellent optical, mechanical, and thermal properties. Sapphire windows are used in a wide range of applications, including laser systems, medical instruments, high-pressure cells, and scientific instruments.
Sapphire is a single crystal form of aluminum oxide (Al2O3), which is one of the hardest materials known to man, making it highly resistant to scratching, abrasion, and wear. It also has excellent optical properties, such as high transparency in the visible and near-infrared regions, and low birefringence.
Circular sapphire windows are preferred for applications that require a circular field of view, uniform transmission of light, and high durability. They can be made in different thicknesses and diameters, with various surface finishes and coatings to suit the specific requirements of different applications.
Sapphire windows can be manufactured using different techniques, such as diamond machining, laser cutting, and polishing. The choice of the manufacturing method depends on the application requirements, the material thickness, and the desired surface quality.
