Wild HEERBRUGG GDR 31
I'm not to sure what these things do, but i am sure you surveyor types do!
This information found online:
This rectangular EDM reflector was designed for the electronic distance meter WILD DI3 (telescope mounted) Distomat. The centre of the reflector sits 38 mm above the tilting axis (as the Wild DI3 sits 38 mm above the telescope axis (line of sight) of thehost theodolite. The froint face of the prism is 94 x 46 mm. The rectangular shape is required because the front lenses of the transmitter and receiver of the DI3 are side-by-side and have each a diameter of 35 mm.
The range of the original DI3 to this prism was given as 300 m minimum in 1973 (and 400 m in 1975). For longer distances ( about 600 m in 1975), the triple-prism reflector GDR11 was available (see item 0420).
The host theodolite is pointed to the yellow triangles underneath the prism before any distance measurement. The back faces of the glass prism of the GDR31 are NOT coated and can/should be cleaned by the user.
For mounting on a tribrach, the GDR31 requires a reflector carrier GRT10, for example.
