The Beseler Topcon line of 35mm cameras used the same lens mount as the Exakta.
Since the instruments are complex in design and difficult to manufacture to clinical standards, only a few manufacturers exist: Topcon, Zeiss, Canon, Nidek, Kowa, CSO and CenterVue.
There are three dominant manufacturers of machine control systems: Trimble Navigation Limited, Topcon Positioning Systems and Leica Geosystems.
Topcon has an office in Technology Park Adelaide at Mawson Lakes, South Australia, and representatives in Sydney.
