Paper Abstract

The instrument for measuring the light scattered from optical surfaces is described. The measurement is carried out using the 253 nm wavelength separated from continuous spectrum of high pressure mercury lamp by a double monochromator. Output signals are detected by a photomultiplier whose sensitivity falls rapidly above 300 nm. The sensitivity of the instrument is about 0.5/3 X 10<8%, where the numbers 0.5 and 3 X 108 characterize the minimal detectable output signal and the maximal one (in reflected light).
