Paper Abstract

A method of spectral correction of detectors used in illuminance meter heads is discussed. An equation is presented by means of which it is possible to determine the monochromatic transmittance (tau) (lambda ) of the filter set which should be used in order that the photometric head be spectrally corrected for the luminous flux falling from the half-space. The spectral characteristics of the filter set for spectral correction of a silicon detector are given for cases in which the luminous flux measured comes from a half-space of uniform luminance distribution. For a head so corrected, the measurement errors due to an inappropriate geometry of the light beams falling on its active surface were calculated. A relation between the magnitude of errors f1 and f1' and the luminous flux incidence on the active surface of the luxmeter head was found.
