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. |
