After a lengthy system rental abroad, we now have another Leica Lasertracker AT960 available for our service and rental business. The system also includes a T-Scan 5 handheld scanner.
Both systems were recently tested, updated with the latest firmware versions, and user calibrations were performed in our own measurement room!
A preconfigured scanning laptop is provided for operating the laser tracker in conjunction with the T-Scan 5 to ensure rapid deployment.
The laser tracker comes with a mobile carbon tripod recommended by the manufacturer, which was developed specifically for the AT960 (according to the manufacturer, lighter tripods may cause vibrations). If you need a mobile tripod, you should therefore use this one (although we had no problems using a mobile Faro tripod in the measurement room either).
System Information:
The T-Scan 5 is a 6DOF line scanner (“Leica T-SCAN 5”) that can only be operated in conjunction with a “dependent” laser tracker—currently the Leica AT901 or Leica AT960. When used with the laser tracker system, the “T-Scan” enables the line scanner to capture a two-dimensional point cloud within the laser tracker’s defined working range (max. 10 m from the LT) at a measurement rate of approximately 210 kHz. The scanning distance is 150 mm ± 50 mm, with a maximum scanning width of 100 mm. The T-Scan is distributed by Hexagon and was originally developed by Steinbichler (now Zeiss). Typically, the scanner is hand-guided by the user, but it can also be guided automatically, for example, by robots in “measuring cells.”
Like the AT960, the T-Scan 5 system is compactly housed in a case, making it suitable for mobile measurement applications.

The manufacturer specifies the following measurement uncertainty:
Measurement uncertainty for spatial lengths (2s) | UL = ±60 µm below 8.5 m |
UL = ±26 µm + 4 µm/m above 8.5 m | |
Measurement uncertainty for sphere radii (2s) | UR = ±50 µm below 8.5 m |
UR = ±16 µm + 4 µm/m above 8.5 m | |
Measurement uncertainty for flat surfaces (2s) | UP = ± 80 µm + 3 µm/m |
