Leica AT401 Absolute Tracker CMM (2011)

Independently certified IEC 60529 usage in even the most
demanding conditions.
Measuring where no other laser tracker can go.
The controller stays out of the user’s way, e.g. attached
to the tripod.
By combining built in WiFi connectivity and on board
battery power, the sensor can operate without any
wires connected at all.
No need to worry about AC (mains) power – the sensor
can run continuously with a new set of batteries able to
be swapped in without interruption
The ATR allows constant tracking and fine positioning with
different reflector types to a typical radial volume of 320 m.
No need to worry about “breaking the beam”: the tracker
automatically locks onto the user providing up to 20% time
savings over traditional laser tracker technologies
The most accurate Leica Geosystems distance meter ever:
The ADM has a resolution of 0.1 micron and a maximum
uncertainty of 10 microns over a full 160 m radial volume.
A built in “survey grade” level to gravity sensor is combined
with a simple three screw leveling quick release platform for
quick and easy machine setup and relocation.
Integrated Overview Camera to allow on-line steering of the
laser tracker for remote or fixed installations
Automatic reading and updating of the environmental parameters avoids inaccurate calculations or wrongly input values.
The absolute angle encoders provide traceable ISO 17123-3
0.5” accuracy with a 0.07” resolution guaranteeing system
accuracy over extremely long ranges.
Due to its low power requirements the sensor can use POE+
technology that combines power and data into a single off the
shelf Cat5 LAN cable.
