Leica AT901
The Leica Absolute Tracker AT901 is a portable laser-based measurement system designed for precise inspection within a spherical range of up to 160 m (525 ft). Featuring PowerLock technology, it automatically re-engages the target when it comes into view, eliminating the need for manual realignment. This lets operators stay focused on the measurement task without worrying about losing the laser beam.
6 Degrees of Freedom tracking with support for T-Scan 5 or T-Probe
Spherical measurement volume up to Ø160 m
High-speed 1,000 Hz data acquisition enables dynamic measurements
PowerLock automatically reacquires the AIFM beam for uninterrupted operation
Ideal for integration into automated measurement systems
Operates with mains power only

features
PowerLock Technology
PowerLock vision technology revolutionizes the way laser trackers are used. Operators no longer need to manually align the laser beam—simply begin measuring, and the tracker will automatically lock onto the target.
Leica Absolute Interferometer (AIFM)
The AIFM combines the dynamic performance of an interferometer with the precision of a single-distance measuring unit. It can seamlessly re-acquire moving targets with a typical lock-on uncertainty of less than 5 μm.
Six Degrees of Freedom (6DoF)
By integrating photogrammetric capabilities into the laser tracker, Leica Geosystems has developed the world’s most advanced PCMM system. This solution offers the flexibility to probe like a fixed CMM, scan like a laser scanner, and track automated processes—all within one system.
High-Speed Dynamic Measurement
With the combined power of AIFM and PowerLock delivering real-time data, the Leica Absolute Tracker AT901 stands out as a powerful tool for demanding measurement tasks, including high-speed and automated applications.
