Vectronix’ heritage dates back to 1921 when Wild Heerbrugg was established as a manufacturer of angle-measuring and other optical precision instruments; based in Heerbrugg, Switzerland, where Vectronix is still headquartered to this day.
The original company merged with Ernst Leitz Wetzlar of Germany in 1986, and became the Leica Group in 1990.
Seven years later, Leica was split into Leica Camera, Leica Microsystems, and Leica Geosystems. The Defense & Special Products Division of Leica Geosystems became a separate company called Leica Vectronix AG in 2002 and joined the French Sagem Group in early 2003.
Vectronix' parent company Sagem merged in May 2005 with the aerospace propulsion and equipment group Snecma to form the Safran Group. Vectronix AG is now a subsidiary of Sagem (Safran Group), and part of its Optronics and Defense Division.
