Scope

What is ISO 21395 ‑ 2 – V-block refractometer method about?    ISO 21395 ‑ 2 is an International Standard that focuses on optics and photonics. It gives the best testing methods for the refractive index of optical glasses.    ISO 21395 ‑ 2 specifies a method to determine the refractive index of optical glass with accuracy within 3 × 10-5 at the wavelength range from 365 nm to 2 400 nm by using the V-block refractometer method.
