Leica GRZ101 360° Mini Prism

Description

The Leica GRZ101 360° Mini Prism is ideal for short range ATR applications. This mini prism offers the best pointing accuracy because of its compact size. It is a light-weight, passive reflectors for use with robotic Total Stations.

The Leica 360° mini prism can be paired together with an GAD103 adapter to enable mounting to all poles with stub fittings.

This type of reflector consists of six corner-cube prisms joined together. The arrangement allows the measuring beam to reflect directly back to its source from any position on the prism set. The even distribution of the prisms provides similar offset and accuracy readings from any side.
