Abstract:

Using a Zeiss leucometer with an incandescent lamp as an example, and starting from the general photometric theory of a spherical photometer and the regularities that describe the fluorescence phenomenon, it is shown that, on such simplified spherical spectrophotometers with zonal filters (of the photometers) with a source of any spectral composition in the UV region (with definite absorbing and emitting properties of white fluorescent test samples), it is possible to obtain the values of the fluorescent admixture to their actual reflectance (radiance) that coincide with the values that would be obtained with an artificial D65 standard radiation source. Experimental results are obtained on an upgraded leucometer that confirm that the artificial D65 standard radiation source can be replaced with an incandescent lamp in working leucometer-type photometers.
