Short description
Clear communication at the intersection between optics design and optics production is important to ensure predictable function of optical components. This includes, in particular, a clear definition and specification of roughness. Often the properties of optical surfaces, specifically surface roughness, are not specified with sufficient precision in illumination optics. As a result, the optics produced often exhibit significant differences from the expected behaviour. This standard presents suitable procedures for specifying the roughness of optical surfaces of illumination optics and/or free-form optics (especially plastic optics), covering the entire range from optically smooth, non-scattering to scattering, rough surfaces. The standard is addressed to all those concerned with the roughness of optical surfaces in the development and manufacture of illumination optics and/or free-form optics (especially plastic optics), in particular to optics design, tool and mould making and optics production (moulding).
