Full Title

Full titles differ between systems:

IPC:

Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light > Systems in which the material investigated is excited whereby it emits light or causes a change in wavelength of the incident light > optically excited > Fluorescence; Phosphorescence

CPC:

Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light (G01N3/00 - G01N19/00 take precedence) > Systems in which the material investigated is excited whereby it emits light or causes a change in wavelength of the incident light > optically excited > Fluorescence; Phosphorescence

Of 12 combined children, 0 exist in both systems.

12 codes are CPC-only extensions.

Note: 4 CPC extensions are marked as secondary classification only.
