G01J1/26 - 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 using a variable element in the light-path, e.g. filter, polarising means using electric radiation detectors adapted for automatic variation of the measured or reference value
