This document specifies the measuring method for the homogeneity of the refractive index of optical glasses by laser interferometry to cope with the grades from ISO 10110-18 and ISO 12123.
Abstract
Overview
specifies laser-interferometric procedures to measure the in optical glass. The standard defines test methods, measurement apparatus, preparation and operation steps, calculation and reporting to support grading systems in and . It is the second edition (2022) and expands measurement options to include PHom, FT-PSI and SCI methods in addition to transmission and oil-on-plate approaches.
