A. Summasv of developments 194.6 - 1952,
1. The dismantling of Zeiss, carried out by the Russians at the end of the war, also
resulted in the destruction of all scientific data and constructional drawings
then in existence. The main task during the years 1946 - 1952 was, therefore,
to replace the records and blueprints required for the resumption of production
at the technical level achieved in 1945. It was also neceSsazy to produce designsfor
:&iol' completely new set of test equipment to replace that which had been removed
by the Russians. Moreover, since many of the firm's leading scientists had been
recruited for work in the U.S.S.R., little original research was possible during
this period.
2. By the end of 1952, these tasks had been largely accomplished, although it has not
yet proved possible to replace all the test equipment lost and the factory still
has to rely to a certain extent on equipment borrowed from various East German
technical institutes. A further obstacle to specialized research has been that
Zeiss was compelled by the Russians to concern itself during this period with var-
ious projects which lay outside its normal sphere of activity; for example, the
manufacture of wire-drawing diamonds, bearing stones,and A-1 air gunnery trainers,
for all of which the necessary designs had to be prepared by Zeiss itself.
3. The following new models were, however, designed during this period and are now
(sic) in-production:
Electronic microscopes (developed in collaboration with the Technical University,
Dresden.)
Pblarization microscopes (with polarization filters)
Reflecting microscopes
Ultra-sonic exciters ('Ultra-Schall Erreger")
16mm sound film projectors
ODocumator* micro-reading equipment

Image measuring devices (that is, stereo-comparators, now in production and stereo-
autocartographs, production of which is shortly to begin) are still based on pre-
1945 designs.
Current Research
5. The head of research at Zeiss is Dr. Paul Goerlich, a specialist on semi-conductive
cells ('"Halbleiter Photozellen'), who succeeded Dr. H. Harting in the stmmpr of
1952.
6. On Soviet instructions, the main effort since then has been directed towards infra-
ectral photometers Arid

A6 This is the most important laboratory at Zeiss and is now engaged An the production
of crystals for use in infrared.-, spectral researchA Work so far has been hampered
by a shortage of large platinum crucibles 1, which are no longer manufactured by the
firms Degussa and Heraeus, who were formerly Zeisass main suppliers. The first
platinum crucible to arrive at Zeiss since the warlwas provided by VEB Quarzschmelze,
Freiberg' in June 1952. Prior to thie9 the laboratory had been working with a single
faulty crucible with a capacity of 1,000 cubic meters. The laboratory's current

B. The cell laboratory
The head of the laboratory is Dipl. Ing. H`annstein. The sum of 1,200,000 BE has been
allotted for the year 1952-1953 for research on photo cells. Current research is
mainly concerned with the following:
