WebIOR. The index of refraction used to calculate the strength of the Fresnel effect. Consists of three values (for red, green and blue) when using "IOR (Advanced)" Fresnel. The coating reflection layer shares similar properties to the base reflection (see Reflection for examples of 'BRDF', 'Fresnel Type' and 'Roughness'). Web1 nov. 2024 · For real materials, the IOR is a function of the wavelength λ of light. This property is called dispersion. For example, the IOR of N-BK7 glass, a common glass for laboratory optics, varies between n = 1.53 at a λ = 400 nm, to n = 1.51 at λ = 800 nm. This may not seem a big difference, but it has significant impact on imaging optics.
