Standardization of terminology, requirements, interfaces and test methods in the field of optics and photonics.

This includes complete systems, devices, instruments, ophthalmic optics, optical and photonic components, auxiliary devices and accessories, as well as materials. Optics and photonics are used in the meaning of generation, handling and detection of optical radiation including signal processing.

Excluded :

  • standardization for specific items in the field of cinematography (ISO / TC 36), photography (ISO / TC 42), eye protectors (ISO / TC 94), micrographics (ISO / TC 171), fibre optics for telecommunication (IEC / TC 86) and electrical safety of optical elements, and general lighting.
