ISO 14997:2017 specifies the physical principles and practical means for the implementation of methods for evaluating surface imperfections. For imperfections specified using the visibility method, two inspection methods are described.

ISO 14997:2017(E) Introduction Standard practice in the optics industry since the 1950s has been to visually inspect optical surfaces for small, localized imperfections and determine if they are acceptable. This document was developed in response to worldwide demand for the standardization of test methods for surface imperfections.

The ISO 10110-7 / ISO 14997 PLUS Scratch Dig standard from Max Levy Autograph is available in three different versions as required to span the wide range of viewing options. All three versions contain two plates with identical patterns. Each version differs in the pattern orientation, permitting usage in various inspection systems.

Standard practice in the optics industry since the 1950s has been to visually inspect optical surfaces for small, localized imperfections and determine if they are acceptable. This document was developed in response to worldwide demand for the standardization of test methods for surface imperfections.

ISO 14997 was prepared by Technical Committee ISO/TC 172, Optics and photonics, Subcommittee SC 1, Fundamental standards. This second edition cancels and replaces the first edition (ISO 14997:2003), which has undergone minor revision to adapt ISO 14997:2011 to ISO 10110-7:2008; the main changes are the deletion of one of the two

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.

Jul 7, 2021 · In both cases, the ISO 10110-7 standard references ISO 14997, a supporting standard that specifies the physical principles and practical means for evaluating surface imperfections.

Aug 1, 2017 · Optics and photonics - Test methods for surface imperfections of optical elements. This document specifies the physical principles and practical means for the implementation of methods for evaluating surface imperfections. For imperfections specified using the visibility method, two inspection methods are described.

These optical defect features simulate, in chrome on glass, scratches & digs (circular defects) of known size. These features can be compared to observed defects in optical surfaces.
