Optics and photonics — Test method for temperature coefficient of refractive index of optical glasses — Part 2: Interferometric method

General information

Current stage: 30.20 Effective date: Feb 4, 2023

Originator: ISO

Owner: ISO/TC 172/SC 3

Type: International Standard

Scope

This document specifies the measurement method of reading the change in optical path length associated with the change in optical glass temperature as the number of cycles of the interference stripe light-dark change using the interferometry, and calculating the temperature coefficient of the refractive index from the change in optical path length.
