Reflectors
Leica Geosystems recommends using the following reflector types:
Hollow corner cube (air path) reflector (Red Ring Reflector (RRR), Break
•
Resistant Reflector (BRR)), consisting of three orthogonal mirrors. The
mirrors are centred in a metal sphere and their reflective surfaces have
a optimized coating.

Small size glass prism (Tooling Ball Reflector (TBR)). For a small size
•
glass prism, the influence of refraction for small entry angles (±15°)
can be neglected. Glass prism reflectors 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.
