Abstract:
Some of the major problems involved in deter mining the tristimulus values of fluorescent paints are determining the speclaal radiance of a fluorescent specimen that is both emitting and reflecting light, irradiating the specimen with sufficient source energy so that the sample emits and reflects an ample intensity of light for spectroanalysis, taking into acnuunt the fact that the angle of illuminating and viewing the specimen influences the results obtained, estab lishing dd maintaining a standard reference sur face, and choosing a suitable source of illumina tion. Adaptation of the CEECKMAN DK-2 spectro photometer to the measurement of fluorescent paint colors involved mainly the development of an instrument assembly capable of determining, with high resolution, the spectral radiance of fluorescent colors. Thiscnncluded a comparison of photomultiplier detectors for sensitivity, the development of improved chart paper for plotting and recording the spectral character of colors, and the production of an enlarged, multicolor chromaticity diagram tosaase eye strain and in sure greater user accuracy.
