2001Development of a single cell flasher system with two illumination ranges in one flash for measurement of up to three IV curves. Production of a complete testing unit with flasher, high voltage, insulation and ground leakage tester for the fully automatic production line of FLABEG.
2000Development of a PC-controlled three channel measuring and load simulation device for registration of IV curves of PV solar cells, arrays and modules. Due to the particular adjustment of measuring electronics and flasher all Dualjunction-, Triplejunction- and Concentratorcells can be measured as well.

1960Development of low-voltage flashers for photography by Hans-Jürgen Berger
In 1960, Hans-Jürgen Berger developed and produced first photographic flashers. Since having sold the first flasher to the German space company MBB in 1973, the company continuously developed conventional high-power flashers into real solar simulators.
In 1997 Detlev Berger took over the company from his father. BERGER Lichttechnik has since developed a wide variety of products for terrestrial and extra-terrestrial solar simulation and testing of solar modules, arrays and cells and increased business at least fivefold.
