BeschreibungDescription

Das Prinzip des Spannungspüfers sind zwei Polarisationsfolien die sich gegenüberstehen. Dazwischen wird die zu verglasende Brille gelegt. Die dabei auftretenden Mängel sind:The principle of the voltage tester is two polarization films that face each other. The glasses to be glazed are placed between them. The defects that occur are:

a) kurze Standfestigkeit der ungeschützten Polfoüena) short stability of the unprotected poles

b) großer Wärmestau durch die im Gehäuseinnem befindliche Glühlampe.b) large heat build-up due to the bulb inside the housing.

Die Aufgabe wird gemäß der Neuerung nach Schuizansprüchen c,d,e,f,g, 1).2},35,4),5),6) gelöst. Ein gemäß der Neuerung gesiaiteier Aufbau zum Prüfen von Spannungen an Brillengläsern, wird anhand der Zeichnung dargestellt.The task is solved according to the innovation according to protection claims c,d,e,f,g, 1).2},35,4),5),6). A setup for testing stresses on spectacle lenses, designed according to the innovation, is shown in the drawing.
