Abstract

An integrating sphere for absolute, hemispherical reflectance measurements on imperfectly diffuse surfaces in the wavelength range between 1250 Å and 3500 Å has been built. The sphere uses a double layer coating consisting of a sodium salicylate film on top of a diffuse white paint. The phosphor coating, under uv irradiation, emits fluorescent radiation in the blue, and the underlying paint layer serves as a diffuser of the fluorescent radiation. The usual problem, encountered in ordinary integrating spheres where direct irradiation of the detector by the sample can lead to erroneous signals, is easily eliminated in the fluorescent integrating sphere by proper filtering of the detector.
