Table shows values from 265 nm to 5 5 microns. Reflectance r as a function of photon energy for single crystals platelets. Open source for use with acknowledgement. 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.

Dodge refractive index in handbook of laser science and technology volume iv optical materials. 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.

Refractive index sapphire is defined as the speed of light in a vacuum divided by the speed of light in sapphire. µm 1 53941 14 28571 complex refractive index n ik n k logx logy ev derived optical constants comments.
