Abstract

Surface treatments and coatings are applied to an optical surface at the end of the component fabrication process. Optical coatings involve the addition of material on the polished optical surface while surface treatments are generally applied to the edges of the components. The type of optical coating depends on the functional purpose of the optical element in the application. In ISO standards, the ISO 9211 series and ISO 10110-9 work in conjunction with each other to provide detailed descriptions of optical coatings, as well as their notation for drawings. ISO 10110-9 contains notation methods for specifying the optical coating on a drawing. While it is certainly possible to use this notation for the specification of a coating, a very detailed description of optical coatings and test methods is provided in the ISO 9211 series. Optical coatings are used to alter the transmission, reflection, or absorption properties of an optical element’s surfaces. Further, these key properties of the surface may be described by wavelength regions, angles of incidence, phase, or polarization. Optical coatings are ubiquitous and a key factor for many optical drawings.
