Sažetak

Methods arc described for the measurement of transmission of protective glasses in the ultraviolet and the visible spectral region. The transmission measurements were performed with a Pulfrich photometer, a König-Martens and a Beckman spectrophotometer. Zeiss universal spectrograph was also used. Measurements with Zeiss spectrograph are discussed in detail. If necessary the radiation intensity was diminished by means of a calibrated set of metal wire screens. The transmission or very dense glasses was calculated using the reciprocity law and the Schwarzschild relation.
