Optics and photonics. Optical materials and components. Test method for refractive index of infrared optical materials. | Status: Current

1 Scope This document provides a standard method for measuring the relative refractive index to the air of infrared materials used in the infrared spectral range from 0,78 µm to 25 µm. This document excludes methods for measuring the refractive index of birefringent materials and methods for measuring the complex refractive index.
