3.1 Reectors
Leica Geosystems recommends using the following reector types:
•
Hollow corner cube (air path) reector (Red Ring Reector (RRR), Break
Resistant Reector (BRR)), consisting of three orthogonal mirrors. The
mirrors are centred in a metal sphere and their reective surfaces have
a optimized coating.

•
Small size glass prism (Tooling Ball Reector (TBR)). For a small size
glass prism, the inuence of refraction for small entry angles (±15°)
can be neglected. Glass prism reectors are recommended for static
points, where it can be pointed towards the sensor unit during the
actual measurement. To impede measurements with large entry angles
of the laser beam, a collar can be mounted on the aperture of the TBR.
