Sapphire is a very useful optical window material for use in the uv visible and near infra red.
Sapphire refractive index wavelength.
Since sapphire is an excellent infrared ir window material it is possible to image the entire chip tool interface in situ in the ir region using a multiple detector ir camera in a manner similar to the observations in the visible wavelength.
The refractive index determines how much the path of light is bent or refracted when entering a material this is described by snell s law of refraction n 1 sinθ 1 n 2 sinθ 2 where θ 1 and θ 2 are the angles of incidence and refraction respectively of a ray crossing the interface between two media with refractive indices n 1 and n 2 the refractive indices also determine the amount.
