Abstract

Within the framework of the German Standards Institution, a study group for the subject "Quality Assessment of Optical Systems" was established in 1968 and was originally assigned to the "Lenses" committee. In view of its importance, however, the study group was transformed into an independent committee in 1972. The committee is composed of representatives of the German companies Elektro Spezial, Leitz, Rodenstock, Zeiss, the Swiss Wild company and representatives of Physikalisch-Technische Bundesanstalt, of the Optical Institute of Berlin Technical University and of the Tubingen Optical Research Institute. It is the purpose of the committee to define measurement conditions that allow proper determination of the OTF. The OTF of any optical or electro-optical system is a physical function determined by the type and the design of the system. Consequently, its measurement must be independent of any specific equipment parameters. In addition, great care must be taken to ensure that the specified physical measurement con-ditions are satisfied within the desired measuring accuracy.
