Abstract

As part of COOMET project "152/DE-a/97 ' Photometry and Radiometry' - International comparison of relative reflectance measurements", measurements were made on a number of samples supplied by PTB Berlin-Friedrichshagen.
The samples were 8 matt, neutral and coloured, opal glasses of Russian production and 1 matt opal glass of German production. Relative measurements of 7 of the samples were made in the specular included geometry against one of the supplied white Russian opals. This Russian opal and the remaining sample, another white Russian opal, were also measured against NPL master matt white standards. Reflectance data for the neutral tiles is presented at 10 nm intervals and that for the coloured tiles at 5 nm intervals.
This report contains the results of measurements made by NPL.
