Abstract:

A discussion based on the theory of measurements using an upgraded Zeiss leucometer (0/d) in which the fraction of UV radiation from the incandescent lamp is controllable was used to obtain a photometric equation (appropriate for any modern leucometer-type photometer) relating the total reflectance factors measured using such an instrument to the total spectral radiance factors for white fluorescent materials measured using a modern spectrophotometer (d/0) with a D₆₅ artificial illuminant at the leucometer effective wavelength. A review of the available experimental results using the resulting equation indicated that it was possible to obtain measurement traceability of the total spectral radiance factors for white fluorescent materials when employing Zeiss leucometer photometers with an incandescent lamp and by using modern spectrophotometers with a D₆₅ artificial illuminant.
