Eumig Research laboratory, Ludwiggasse
Following the suspension of radio and television manufacture, a Research Department was established in 1964 with personnel from the former radio and TV laboratory, in the Ludwiggasse in Vienna’s 19th District, with the aim of investigating new equipment for image storage and reproduction.
Individual areas of focus were:
Video cameras: Black-and-white and colour cameras, making use of "Vidicon" receiver tubes, were manufactured for a wide range of applications (monitoring and surveillance, video recorder accessories, etc.).
Film scanners: Equipment for the reproduction of narrow-gauge films (8 mm) on a video screen; a model with an oscillating mirror as optical compensation for uniform film movement was worked on.
Video recorders: Co-operation with C.T.I., Cartridge Television Incorporated, of the USA, in the development of a b/w video camera (VC550), with the optical system of the Mini 3, as an accessory for a video recorder for home use.
Co-operation with a German company on a longitudinal video magnetic tape recording process.
Optics testing system: An automatic testing system for projection lenses was developed.
Lasers: Gas lasers from in-house manufacture (glass blowing facility, high-vacuum, gas filling, etc.) for teaching in schools and for holograph research. The prototype of a ruby laser was produced.
Holography: The combination of holography and video technology made it possible to develop a device for the non-destructive material testing of turbine blades and automobile tyres.
Thin layers: Development of vapour-deposited hard coatings for scratch-resistant coating of lenses and highly-reflecting mirrors for lasers.
Laser range-finders: In co-operation with the Technical University of Vienna, Dr. Riegl developed a laser range-finder based on the radar principle. This marked the beginning of a high-tech company in Austria’s Waldviertel district.
