Standard Practice for Obtaining Bispectral Photometric Data for Evaluation of Fluorescent Color

Importancia y uso:

5.1 The bispectral or two-monochromator method is the definitive method for the determination of the general (illuminant-independent) radiation-transfer properties of fluorescent specimens (2). The Donaldson radiance factor is an instrument- and illuminant-independent photometric property of the specimen, and can be used to calculate its color for any desired illuminant and observer. The advantage of this method is that it provides a comprehensive characterization of the specimen’s radiation-transfer properties, without the inaccuracies associated with source simulation and various methods of approximation.

5.2 This practice provides a procedure for selecting the operating parameters of bispectrometers used for providing data of the desired precision. It also provides for instrument calibration by means of material standards, and for selection of suitable specimens for obtaining precision in the measurements.
