The Leica Absolute Tracker AT901 is now equipped with PowerLock. This active
vision technology automatically locks onto any moving target without user intervention.
By utilizing a vision system built into the Leica Absolute Tracker AT901 the sensor
can now determine where a target is without the need for the laser beam to be locked
on.
The Leica Absolute Tracker AT901 locks on to the target automatically as soon as
it is within view of the sensor. This allows the operator to focus on the part
they need to measure without constantly worrying about the laser tracker and whether
or not they have broken the beam.

Depending on your measurement needs, there are three Leica Absolute Tracker
AT901 types available.
Leica Absolute Tracker AT901-Basic
If your application requires positioning machines, fixtures or jigs, or
if you are in the business of installing and aligning machine tools, roll mills,
presses or gantry based machines, the Leica AT901-Basic is your tracker.
Operating solely with a reflector, it is optimized for inspections within a
typical measurement volume of up to 160 m (525 ft), and comes standard
with our Leica Absolute Interferometer and PowerLock technologies.
Leica Absolute Tracker AT901-Mid Range
Since the introduction of the Leica T-Products in 2004, practically all
leading automobile manufacturers have joined the ranks of our customers. When
a reflector simply won't cut it because there is no clear line of sight to the
part you are trying to inspect, the part is hidden or sunken deep beneath surrounding
sheetmetal, or because you need to reverse-engineer a part right there on
the spot, the Leica AT901-MR is all you will need. When coupled to the
Leica T-Scan, T-Probe, or T-Mac the Leica AT901-MR gives
you a measurement volume of up to 18 m (59 ft). Of course, it can
also be used with a standard corner cube, in which case its measurement volume
goes up to a full 50 m (164 ft). The sensor is designed for large vehicle
size objects and of course comes standard with our Leica Absolute Interferometer
and PowerLock technologies.
Leica Absolute Tracker AT901-Long Range
This is the laser tracker that set the new benchmark for aerospace and other large
scale precision measurements such as windmill blade inspection or industrial machinery
alignment. It gives you hand-held wireless probing (Leica T-Probe),
hand-held contactless scanning (Leica T-Scan), and full machine
control abilities (Leica T-Mac) in a volume of up to 30 m (98 ft).
Of course, it can also be used with a standard corner cube, in which case
its typical measurement volume goes past 160 m (525 ft). This is the
laser tracker that set new standards for usability with the Leica Absolute Interferometer
and PowerLock, and continues to be the best selling 6DoF laser tracker in the
world.

Benefit
|
|
PowerLock
|
For the first time in the history of laser trackers, the laser
beam moves to the user, not the other way around.
|
|
The AIFM or“Absolute Interferometer” combines the absolute
measurement from the ADM with the almost instantaneous update rate of the interferometer
to produce the most accurate, stable, technologically mature distancing
unit we have ever created.
|
Waiting for the tracker to“lock-on” is now a thing
of the past. Simply catch the beam and you are measuring again without delay.
No matter if you are using a reflector, Leica T-Probe, Leica T-Scan
or Leica T-Mac, the AIFM can instantly re-establish a broken laser beam
and immediately start measuring the moving target.
