Leica GRZ4 360 Prism

Leica GRZ4 360 Prism

The GRZ4 360º prism is recommended for all work with remote-controlled instruments when the prism is mounted on a plumb line. The rubber mount at the top and bottom of the prism protects the prism if the plumb line falls over. The prism is supplied in a padded transport bag. The GRZ4 has complete 3D point accuracy of 5.0 mm.

However, if alignment is done directly to any of the six sub-prisms, an accuracy of better than 2 mm can be achieved. Yellow arrows placed on the upper rubber mount make it easy to correctly align the prism.

ATR range of 600 meters. Prism constant +23.1 Axis height: 86 mm Offset: - 11 mm
