Leica Laser Tracker AT401

Leica Laser Tracker AT401

All accuracy is determined with Leica Geo-systems 1.5” Red Ring Reflectors (RRR) and 2 seconds per point measurement mode in stable ambient conditions. Full range is defined at 1.5 to 80 meters outside the laser tracker in +/- 45˚ vertical range.

All accuracy is given in maximum permissible error (MPE). The typical yield is half of the MPE.

AT401: +/- 15µm + 6µm/m
