Leica T-Probe

The Leica T-Probe interfaces with the Leica AT901 laser tracker to provide a 6 degree of freedom “Walk-Around” armless wireless probing system. The T-probe allows measurement of hard-to-reach points for parts up to 30meters in length and is ideal for the aerospace and automotive industry.


  • Smaller, lighter and more convenient than comparable solutions

  • Largest armless operation measurement volume of up to 30 m, reducing inspections by min. 50%

  • Wider acceptance angle than any comparable system: pitch ±45°, yaw ±45°, roll 360°

  • Battery-powered for wireless operation and increased productivity

  • PowerLock: For the first time in the history of laser trackers, the laser beam moves to the user, not the other way around.

  • Extended battery life with flexible “sleep” mode

  • Automated probe identification reduces operator errors

  • User-assignable multi-function buttons for individual application functionality for all buttons

  • One-hand operation with left/right-hand functionality

  • Renishaw-compatible with a wide range of styli available, incl. 100 mm, 200 mm and longer

  • Visual feedback for battery, in-view and in-distance status and for process information

  • Acoustic process information feedback

  • Insensitive to environmental light

  • Point rate output of 1,000 points per second

  • Tracking speed > 1 m/s

  • Measurement uncertainty of 3D Point (MPE): U3d = 100 µm if under 7 m, U3d = 30 µm + 10 µm/m if greater than 7 m

  • Measurement uncertainty of spatial length (MPE): Ul  = ± 60 µm if under 8.5 m, Ul  = ± 7 µm/m if greater than 8.5 m

  • Measurement uncertainty of sphere radius (MPE):Ur  = ± 20 µm + 2 µm/m

  • Precise quick release and automated stylus recognition for exchanging styli without calibration
