Leica Absolute Tracker - AT901

The Leica Absolute Tracker AT901 from Leica Geosystems is a portable measurement system that relies on a laser beam to accurately measure and inspect in a spherical volume of up to 160 m [525 ft].
The Leica Absolute Tracker can gather 3D coordinates in 3 ways:
1-by following a small mirrored sphere, also known as a reflector;
2-by tracking a Leica T-Probe, a hand-held “walk-around” wireless contact probe;
3- by tracking a Leica T-Scan, a contactless high-speed laser scanner.
Powerlock, advantage: For the first time in the history of the Laser Tracker the laser beam moves towards the user and not vice versa.

By combining the absolute measurement of ADM with the almost instantaneous update frequency of the interferometer, the AIFM or "absolute interferometer" appears to be the most accurate, stable and technologically advanced measuring instrument so far made by Leica.

Whether you are using a reflector, the Leica T-Probe, the Leica T-Scan or the Leica T-Mac, the AIFM is able to instantly restore the interrupted laser beam and directly start the measurement of the target in motion. Equipped with a robust structure, extremely high thermal stability, a compact interior design and a tracking sensor head that does not emit heat, allows continuous operation as per specifications in harsh industrial environments, without having to make frequent compensations.
The Leica Absolute Tracker AT901 only requires one calibration per year.

It has the only technologically advanced portable CMM system (with six degrees of freedom) able to perform measurements such as a fixed CMM, scan like a laser scanner and perform tracking in automated applications: all in one system.

With a weight of just 22 kg and a length of 62 cm, the instrument consists of a lightweight structure with compact dimensions, easily transportable and installable by a single person, fully compliant with the standards for safety at work.

With ADM/IFM with small diameter radius it is possible to use 0.5' reflectors for the entire measuring range, and thanks to the versatile mounting it is possible to mount vertical or horizontal that guarantees versatility in the measurement volume. * **
* Typical results included in specifications.
** Cannot be used with the T-Cam in horizontal position.

Leica 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 901 - Mid Range

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, TProbe, 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.

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.
