Early Television Camera Tubes

German Minature Super Iconoscope

Early Television

Sometime in the early-mid 40s Telefunken developed a minature "super iconoscope" for use in Germany's Tonne guided missile systems. An excerpt from a British document written after the war describes the tube.

From Jochen Gittel:

This camera tube was used to televise the 1936 Berlin Olympic Games. It was developed by Dr. Heimann of the Post Office Ministry in Berlin. The cathode had a life of only a few hours. Every night after use, the electron gun (in diagonal tube) was removed and a new one inserted. The tube was then evacuated for use the next day.

Comments from Peter Scott:

I know this derives from information posted here .

but I am very skeptical of the accuracy of the dating used.

I know that Telefunken bought the rights to manufacture the iconoscope from RCA and I suspect this would have been a standard iconoscope very similar to the RCA tubes at the time.

I think this is a photo of a Telefunken iconoscope

The sugggestion from the German site is that the massive "Fersnehkanone" cameras used at the 1936 Olympics were fitted with "Super Ikonoscope" camera tubes. I think this is unlikely if for no better reason than that Lubszynki & Rodda working for EMI were granted a patent for the "Super Emitron" in February 1936 having applied in May 1934 and surely this would not have been granted if Telefunken had the prior art.

I strongly suspect that the German "Super Iconoscope" dates from several years later than the 1936 quoted.

I believe the miniature super iconoscope in the photograph was developed much later for use in television guided weapons.
