Optics and photonics - Optical coatings - Part 4: Specific Test Methods
OP1.9211 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 OP1.9211 provides specific test methods for optical coatings.
