Reflectivity per surface
WebMay 28, 2024 · This plot gives the measured reflectance (per surface) at normal incidence of our 5 mm thick, AR-coated sapphire window for 1.65 - 3.0 µm. The average reflectance is <1.0% per surface within the shaded … In the diagram on the right, an incident plane wave in the direction of the ray IO strikes the interface between two media of refractive indices n1 and n2 at point O. Part of the wave is reflected in the direction OR, and part refracted in the direction OT. The angles that the incident, reflected and refracted rays make to the normal of the interface are given as θi, θr and θt, respectively.
