Sensoren für UV-Strahlung

(PresseBox) (Berlin, )
Bei vielen technischen Anwendungen muss UV-Strahlung genau gemessen werden. Auch beim Sonnenlicht wollen wir wissen, wie viel UV-Strahlung auf unsere Haut trifft. UV-Photodetektoren basieren auf unterschiedlichen Materialien - je nach Anwendung sind bestimmte Eigenschaften wichtig. Das Ferdinand-Braun-Institut untersucht geeignete Materialien und ent­wickelt GaN-UV-Detektoren.

Wird UV-Strahlung in einer Technologie eingesetzt, zum Beispiel zur Desinfektion von Wasser, darf die Strahlung weder zu schwach noch zu stark sein. Da UV-Lichtquellen im Laufe der Zeit an Intensität verlieren, kann die Strahlungsdosis nicht direkt gesteuert werden, sondern ein Sensor muss die tatsächlich abgegebene Leistung messen. Photodetektoren für den UV-Spektralbereich basieren auf unterschiedlichen Materialien: Derzeit sind Mrhqmephukdwxhg (EaR) fwz Izsaprodjpxwoj (CxC) yko gnc Zahat vxgvokjvrx. Qc.
