BS ISO 9211-2:2010 pdf free.Optics and photonics一 Optical coatings Optical properties.
BS ISO 9211-2 Iso 9211 identifies surface treatments of components and substrates excluding ophthalmic optics (spectacles) by the application of optical coatings and gives a standard form for their specification. It defines the general characteristics and the test and measurement methods whenever necessary, but is not intended to define the process method.This part of ISO 9211 indicates how to specify optical properties of coatings and to represent their spectral characterization graphically.

Terms and definitions For the purposes of this document, the terms and definitions given in ISO 9211-1 apply.
Optical properties to be specified When specifying optical properties, the refractive indices of the incidence medium and the emergent medium shall be given. The polarization state of the incident radiation shall also be indicated if the angle of incidence, 0, is different from zero or a range of angles of incidence is given. If there is no indication, unpolarized radiation is assumed.
The optical properties (), p(), a(A), D(A) and sO() of a coating shall be specified by using the formulation given and explained in 6.2 in order to provide a comprehensive description of a coating with regard to its minimum set of optical properties. Other optical properties like scattering or colorimetric parameters etc. shall be subject to agreement between supplier and user if appropriate.
The measurement conditions for the spectrophotometric characterization shall be subject to agreement between supplier and user. These conditions depend on the principle of the measurement method and the instruments used, including the angle of incidence, the state of polarization, the spectral range and bandwidth of the measurement beam， etc. and shall be recorded in sufficient detail to enable verification of the measurement.BS ISO 9211-2 pdf download.
