Optics and photonics. Optical coatings - Environmental durability Ingestion-build-86103 Cryogenic valves are designed to1 Scope 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. It is not intended to define the process method. This part of ISO 9211 specifies categories of use for optical coatings and identifies which
