Optics and photonics. Test methods for surface imperfections of optical elements. Machine vision | Status: Current

1 Scope This document provides guidance for the use of machine vision to objectively assess grades of surface imperfections as defined on a drawing using ISO 10110‑7 with equivalent results as those obtained by applying the inspector-based methods described in ISO 14997‑1. This document also gives guidelines on how to setup a machine vision device regarding fidelity, repeatability and reproducibility, based on the dark field detection principles of ISO 14997‑1.
