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. Web11 apr. 2024 · When the IOR gets up too high, the focal point will be so close that the rays coming out the other side will scatter and the caustic pattern will either be soft or difficult to see. The IOR of air is 1.0, water is 1.3, typical glass is ~1.5, and usually the highest refractive IOR found easily in nature will be gemstones like diamond, which is ~2.4.
