Rounded average PRR
Typical values for average conditions and average ambient brightness. In bright sunlight, the max. range is shorter than under an overcast sky.
The 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. Range ambiguities have to be resolved by multiple-time-around processing.
Typical values for max. effective FOV 75°, additional roll angle ± 5°
If more than one target is hit, the total laser transmitter power is split and, accordingly, the achieveable range is reduced.

Limitation for range measurement capability, does not consider laser safety issues! 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. Measured at 1/e2 points, 0.35 mrad corresponds to an increase of 35 mm of beam diameter per 100 m distance.
