G01J1/20 - CPC Classification

Classification description:

Photometry, e.g. photographic exposure meter by comparison with reference light or electric value provisionally void intensity of the measured or reference value being varied to equalise their effects at the detectors, e.g. by varying incidence angle

Sub-classes:

G01J1/22 » using a variable element in the light-path, e.g. filter, polarising means 13
G01J1/28 » using variation of intensity or distance of source 11
G01J1/34 » using separate light paths used alternately or sequentially, e.g. flicker 1
