Rounded values.
Setting of intermediate PRR values possible.
ypical values for average conditions. Maximum range is specified for flat targets with size in excess of the laser beam diameter, perpendicular angle of incidence, and for atmospheric visibility of 23 km. In bright sunlight, the max. range is shorter than under overcast sky.
Ambiguity to be resolved by post-processing with RIUNITE software.
Flat terrain assumed, scan angle ±45° FOV.
If more than one target is hit, the total laser transmitter power is split and, accordingly, the achieveable range is reduced.

Accuracy is the degree of conformity of a measured quantity to its actual (true) value. Precision, also called reproducibility or repeatability, is the degree to which further measurements show the same result.	One sigma @ 150 m range under RIEGL test conditions. User selectable, setting of intermediate PRR values possible. Measured at the 1/e points. 0.35 mrad corresponds to an increase of 35 mm of beam diameter per 100 m distance. Measured at the 1/e2 points. 0.50 mrad corresponds to an increase of 50 mm of beam diameter per 100 m distance.
