The production program was supplemented by compasses, tweezers, levelling devices, dioptres and other fine mechanical products. In 1767, VoigtlГ¤nder invented two important tools: a linear device for natural and tapered gauges, and a circular device for elevation, astrolabe, and cartography etc., including, a screw cutting machine, a metal lathe and finishing rollers for sheep wool and silk factories. Through Johann VoigtlГ¤nder's skilful achievements, the Minister of State of the Habsburg Monarchy- Prince Wenzel von Kaunitz, drew attention to VoigtlГ¤nder and Empress Maria Theresa of Austria granted VoigtlГ¤nder in 1763 a so-called trade 'Protection Decree' (German Schutzdekret/Schutzdecret): 'on the making of mathematical instruments and on an unspecified number of workers', upon which VoigtlГ¤nder founded his own workshop and whereby he could sell his products relatively unrivalled. Johann Christoph VoigtlГ¤nder (Novemin Leipzig вЂ“ Jin Vienna), the son of a carpenter, came to Prague in 1755, and to Vienna in the same year, and worked from 1757 to 1762 in the workshop of Meinicke, who produced mathematical instruments. VoigtlГ¤nder produced mathematical instruments, precision mechanical products, optical instruments, including optical measuring instruments and opera glasses, and is the oldest name in cameras. VoigtlГ¤nder was founded in Vienna, Archduchy of Austria, in 1797, by Johann Christoph VoigtlГ¤nder.
