Description

Einriohtung 8tp* Sicherung von ildwandlerröhren gegendia Einwirkun von Tages-und Fremdlicht Bekanntlich sind Bildwandlerrohren außerordentlich empfindlich gegen Tages- und Fremdlicht. Die auf Infrarot-Strahlen ansprechende Photokathode erleidet durch ein derartiges Licht Dauerschäden, die die Empfindlichkeit und Qualität der Röhre stark herabsetzen. Bisher wurden Bildwandler nur durch aufgesetzte Kappen gegen dieses schädliche Licht geschützte die zum Gebrauch abgenommen wurden. Da dieses Abnehmen völlig in der Willkür der bedienenden Personen liegt. treten unvermeidbar Schäden ein, die nach relativ kurzer Zeit die Bestückung mit einer neuen Röhre bedingen, was naturgemäß außerordentlich kostspielig ist. Installation 8tp * Securing of picture converter tubes against the effects of daylight and extraneous light It is well known that image converter tubes are extremely sensitive against daylight and extraneous light. The photocathode, which responds to infrared rays, suffers permanent damage from such light, which greatly reduces the sensitivity and quality of the tube. So far, image converters have only been protected against this harmful light by attached caps which have been removed for use. Since this weight loss is entirely at the discretion of the operator. damage inevitably occurs, which requires a new tube to be fitted after a relatively short period of time, which is of course extremely expensive.

Dieser Nachteil wird durch die Erfindung beseitigt. Aufgabe der Erfindung ist es also, Bildwandlerröhren zuverlässig gegen die Einwirkung von Tages-und Fremdlicht zu schützen. Diese Erfindungsaufgabe wird im wesentlichen dadurch gelöst, daß ein in die Optik des Bildwandlers eingeschalteter Lichtverschluß durch Druck auf das üblicherweise vorgesehene Okulargummi über geeig- Tte Nbepa. giHigami-1 geBffn w& m sieh ei Bfaslassen des druckes sels&% wi. ; ey ae&la. eß e eragus &9s Ruckes m (H&. aEmmi.
