In April 1953, a conference on infrared techni r'l-s crag held ir. -T :u.. T11- conference was attended by Paul Goerlich of VEB Ca* Zeiss, ] itag. Baas of the Central Institute for Telecommunication Engineering, Di^l. Ing. ",V'enderlich of the Telecommunicntjon Engineering Plant at Berlin- 0berschoeneweide#and Dr. Eckardt of the Institut fuer Festkoerperinrschung (Laboratory for Research ',cork on Solid Bodies) in Berlin. lit the conference, Dr. Coerlich proposed that the development of image converters be started at the Zeiss orkd. The other participants of the conference rejected this proposal and said that the development of this equi'ment #hq d take place at the Berlin-Oberschoeneweide Telecommunicr:tion Engineering Plant because such development work had already been started there by Dr. Eckardt wholin the meantime,had left the plant. 2. From rumors herd in December 1954 it w-s inferred that the development of image converters h d been discontinued at the Tel.ecommunictition Plant and shifted to VEB. Carl Zeiss Jena and VEB Zeiss Ikon Dresden. 3. In January 1955, work on the development of raliation receivers was being done in Jena. Dr. Krohs, the chief of 1*e Pho ll Laboratory, and Herr Hauenstein did the main work on infrared techniques. In the Electric Laboratory, Karl Prinz t: -worked on thermocouple elements and bolometers functioning or all wave lengths but, of lesser sensivity than the photocells, which operate only on wave lengths up 'co 3 y1,i. 4. The type KRS=5 crystals produced in Jena have a permeability of 95 % after deducting reflex losses of 80 The permeability has no absor=tion maxima or minima and evenly extends from 0.8 to 0.4 p. The absor-tion sets in below the 0.8 i point. The quality of the material makes it possible to manufacture from it plane parallel glass 60 mm thick. Frior to the dismantling of the plant by the Soviets it had been possible to manufacture such glass up to mm. Cround prisms have not yet been manufactured in n.z.. ft. flTinte 1853, no quartz crystals had been produced in autoclaves. It was dcubtcd by Harr Dittner,3that the material required for autoclaves mould ever be obtained by the firm. 25X1 High-quality Est proof ataeisewhich at a temperature of 5000C may be C SSIFIC TION ATE NAVV NSRB ARMY AIR FBI H IMIGLMON 1. r CD N.O.

'.'ork on the development of the electron-multiplier tube was continued. The first set including the mains unit was to be delivered to Jena University by mid-December 1954. In early January 1955, it was unknown y,r thy, ?ai: had actually been delivered. The development of the e,uipinent had been cortinued by Herr Hauenstein after Dr. Buch had gone to the Electric Engineering College at Ilmenau as a lecturer Lam, vacuon techniques. 6. In the summer of 1954, many Czechs, Poles, Hungarians, and Rumanians visited the :aeiss works in Jena. 7. By late 1954, real progress had made on the development of tn. iiodel Opremaaelectronic co.npu-'or developed by Dr. Herbert Kortum at the-Lain Development Tepartment (i n.tiict:lungshauptabteilung) (EHL) in Jena. Dr. Kortum nlanned to concentrate the development of Putomati.c control devices for machine tools in Jena. The EIiL had already received =;n order for the development of automatic measuring and control devices or large lathes. Dipl. Ing. Dietrich of Development Bureau 0 viorked on the project. Electric measuring sets were also said to be scheduled for development. The model Oprema electronic computer,the operations of which could be preset, was to be put into operation on 1 Kay 1951. The equirment which is a "4-Address" (?) computer, was designed as a twin machine. The second electronic conaputer was scheduled to be completed in June 1955, The latter set is to be used at the Zeiss 'Roo'tcs or the optical computing. Final decisions on the personnel to operate the set hat. not ;rat b:cn taken. 9;( In late January 1955. Dr. Ing. N. Joachim Lehmann of the Dresden Institute of Technology visited the Zeiss VVorks in Jena. On this occs sion it was le,-rnec th:,t Prof. Dr. ;oillers and Pr, Trg. it-h an: of hiia Dresden Institute of Technology developed two electronic computers which were built by the HFT-Ceraetery~erk at Chemnitz (apparatus plant for radio and telecommunicf~tion engineering techniques). The computer was a so-callcd one-address set operating at a speed eight times higher then that of the Oprema computer. Each of the sets built at Chemnitz is fi?'tac in 600 triodes expressly manufactured for this purpose. Dr. Lehmaxin stated that the storage unit of the set still worked In an unsatisfactory way and thr:t difficulties had also been experienced in the making of construction drawin -s. One of the sets produced as delivered to the Dresden Institute of Technology, while thp other computer r mained irr Chemnita. It was not intended to manufnetur?'' more of these electroh'iic computers. Lehmann also said th't Czechoslovakia had developed a new electronic computer designed as a 5-address relay computer with :O contact planes 10.
