Titles differ between systems:

IPC: Arrangements for eliminating effects of disturbing radiation; Arrangements for compensating changes in sensitivity

CPC: Arrangements for eliminating effects of disturbing radiation; Arrangements for compensating changes in sensitivity (for adjusting of solid angle of collected radiation G01J5/07; means for wavelength selection G01J5/0801)

Full titles differ between systems:

IPC:

Radiation pyrometry, e.g. infrared or optical thermometry > Constructional details > Arrangements for eliminating effects of disturbing radiation; Arrangements for compensating changes in sensitivity

CPC:

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

IPC defines codes here since 2022.
