Description
dichte betrug konstant 0,09 J/cm . Die Expositionszeit wurde über einen breiten Bereich variiert, und die spektralen Durchlassxgkeiten der belichteten Teststücke wurden mit einem Spektrophotometer ausgemessen. Die Testergebnisse sind in der Fig. 2 dargestellt. Die Exposition mit der starken UV-Lampe bewirkte, daß die Teststücke des Glases sich geIblieh-braun verfärbten und die Verfärbung vertiefte sich bei Verlängerung der Expositionsdauer. Nach Abschluß der Exposition blieben die Testglasstücke ohne Anzeichen eines Ausbleichens gefärbt.
