Wenderlich of the Telecommunication Engineering Plan a Berlin- ILLEGIB
Oberschoeneweide and Dr. Eckardt' of the, Institut fuer Festkoerperfvvsc`-----
(Laboratoryfor lesearch Work on Solid Bodies) in Berlin. At the ILLEGIB
conference, Dr. Goerlich proposed that the development of image converters

e such development work had already been started
i. in the meantime,}had left the plant.
2. From rumors heard in December 1954 it was inferred that the development
of image converters had been discontinued at the Telecommunication Plant
and shifted to . VER Carl Zeiss a and IM VEB Zeiss Ikon
Dresden.
3. In January 1955, work on the de cation receivers was being '-
done in Jena. Dr. Krohs, the ch ell Laboratory, and HCTILLE GIB
Hauenstein did the main work on ques. In the Electric
Laboratory, Karl Prinz worked on thermocouple elements and
bolometers functioning s all wave lengths but of lesser sensivity than
the photocells.1 which operate only on wave lengths up to 3 }i.
4. The type KRS-5 crystals produced in Jena have a permeability of 95 % A~li
after deducting reflex losses of 80 %. The permeability has no absorption
maxima or minima and evenly extends from 0.8 to 0.4 P. Ths absorption
sets in below the 0.8 z point. The quality of the material makes it
possible to manufacture from it plane parallel glass 60 mm thick. Prior to
the dismantling of the plant by the Soviets it had been possible to ILLEGIB
manufacture such glass up to a thickness of 120 mm. Ground prisms have

Electric measuring sets were also said to be scheduled for development.

On 29 March, a Soviet
official from Berlin who previously had been

adviser to the Soviet Minister of Machine Construction, visited the Zeiss
Works and also inspected the electronic computer. The Leuna Works were
also greatly interested in an electronic computer of the type developed
by the Zeiss Works.
11. Since early 1955, the most important project handled by EHL had been the
development of a gyro-controlled aerial mapping camera. The development
work w.ps controlled by Dr. Kortum.

Ing. Lensky who is attached to Dipl. Ing. Dietrich stated that electron-
multiplier tubes were being built at the Zeiss Works. Details were not
available.
16. Air force training sets of type Al were being built at Dr. :Ing. Knothe's
Department (ELGMMDepartment) of the Suedwerk (Southern Plant). During
