Introduced: September 1968

Title

Titles differ between systems:

IPC: Optical coatings produced by application to, or surface treatment of, optical elements

CPC: Optical coatings produced by application to, or surface treatment of, optical elements (G02B1/08 takes precedence)

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

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)

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
