Roeschlein was a lens maker founded shortly after WWII by Stephan Roeschlein in Bad Kreuznach, Germany.
Previously, Roeschlein had been working as a lens developer at Hugo Meyer-Görlitz until 1936. Among his inventions were the prototype of the Meyer Telemegor series and several variants of the famous Meyer Primoplan. In 1936, Roeschlein left Meyer-Görlitz to become Technical Director of Schneider-Kreuznach as a successor to Albrecht Tronnier, inventor of Xenar and Xenon lens designs.
After the war, Roeschlein founded his own lens-manufacturing company, which was specialized in designing unique and small-series lenses made to customer specifications. Besides that, Roeschlein produced some of his own lens desigs for consumer cameras, focussing on the Braun Paxette rangefinder system. The Roeschlein Luxon was, arguably, the most interesting lens made for that system, and is a sought-after collector's item today. Interchangeable high-quality Roeschlein lenses in other mounts, including Exakta and M42, were made in small numbers. Additionally, Roeschlein provided rather simple fixed lenses for some cheap 1950's cameras like Luxette and Paxina.
Roeschlein's company was taken over by Sill Optics, Selb, in 1962, leaving the consumer market but continuing to make special-purpose lenses. As of today (2012), Sill is still in business.
