Paper Abstract

Apart from the measurement of illuminance on the plane surface, it is also necessary to measure half-cylindrical illuminance (according to the rules and other recommendations). The luminous flux incident on the photometer's head has to be corrected (according to the definition of the luminous flux). It is possible to do this spatial correction using light fibers having very small numerical aperture (NA). Authors present this kind of construction.
