JIS B 7072-2 – Measuring method for temperature coefficient of refractive index of optical glass — Part 2: Interferometry
JIS B 7072-2:2020 specifies a measuring method in which the variation of optical path length with temperature change of optical glass is read by the number of periods of brightness changes of interference fringes using the interferometry method, and the temperature coefficient of refractive index is calculated from the variationof the optical path length.
