G02B 1/11

Anti-reflection coatings

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Optical elements characterised by the material of which they are made; Optical coatings for optical elements > Optical coatings produced by application to, or surface treatment of, optical elements > Anti-reflection coatings

CPC:

Optical elements characterised by the material of which they are made; Optical coatings for optical elements > Optical coatings produced by application to, or surface treatment of, optical elements (G02B1/08 takes precedence) > Anti-reflection coatings

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 2015.
