【Abstract】 Three calculating methods for oxide glasses infrared optical constants including refractive index n r  and extinction coefficient k were discussed using numerical analysis, geometrical optics and electromagnetic theory. A simple method was deduced for calculating refractive index and extinction coefficient. It provides a useful way for study of the infrared oxide glass materials.更多还原
