DIN ISO 10110-7:2016-05

ISO 10110 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 part of ISO 10110 specifies the indication of the level of acceptability of surface imperfections within the effective aperture of individual optical elements and optical assemblies. These include localized surface imperfections, edge chips and long scratches. It is to be noted that the acceptance level for localized imperfections is specified taking into account functional effects (affecting image formation or durability of the optical element) as well as cosmetic (appearance) effects. This part of ISO 10110 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 visibility of imperfections on components or in optical assemblies.
