NBN ISO 10110-7:2021

ISO 10110 (all parts) specifies the presentation of design and functional requirements for single optical
elements and for optical assemblies in technical drawings used for their manufacture and inspection.
This document specifies the indication of the level of acceptability of surface imperfections within a
test region on individual optical elements and optical assemblies. These include localized surface
imperfections, edge chips and long scratches.
The acceptance level for imperfections is specified, taking into account functional effects (affecting
image formation or durability of the optical element), as well as cosmetic (appearance) effects.
This document applies to transmitting and reflecting surfaces of finished optical elements, whether
or not they are coated, and to optical assemblies. It allows permissible imperfections to be specified
according to the area affected by imperfections, or alternatively by the visibility of imperfections, on
components or in optical assemblies.
