WebRefractive Index Database. The table below contains links to refractive index data for common materials. Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin-film thickness measurement. WebWe define the index of refraction, n, of a material to be n = c v, where v is the observed speed of light in the material. Because the speed of light is always less than c in matter and equals c only in a vacuum, the index of refraction (plural: indices of refraction) is always greater than or equal to one. WebBy contrast, fused quartz has a lower refractive index n ≈ 1.95, but a more significant absorption (α ≈ 2.5-3.0 cm −1 ) [20]. These lead to an etalon peak separation of ∆f ≈ 88 GHz for ... ralf gassen
