Leica AT403 Laser Tracker

Leica Absolute Tracker AT403 is an universal measuring system with 6 degrees of freedom. It has an extreamly large measuring volume of up to 320 meters and is compatible with the Leica B-Probe.



We are selling a demo used Leica Absolute Tracker AT403, used very little, mostly for training classes. Looks and runs like new. Manufactured in 2019 and Hexagon Manufacturing Intelligence Absolute tracker Leica AT403 is a self-contained measuring system in a compact and convenient housing, a universal portable solution for metrological tasks, more portable than others in the market. Leica Absolute Tracker AT403 allows to make measurements with very high speed, it is very simple in operation and has a strong construction. This tracker is a mobile set of low-cost innovations that has no analogs in the field of portable measurements. The improvements relate to the acceleration of discrete and continuous measurement processes. Wi-Fi access point added, and the possibility of ”hot” replacement of batteries. The design of the housing has a degree of protection IP54, which makes it possible to use the tracker practical in any conditions. It is designed for operation in the temperature range from -15 to +45º? Has a built-in system of environmental monitoring.

The Leica Absolute Tracker AT403 retains the properties of its predecessors, such as the PowerLock function, full battery operation and a high measurement volume of 320 meters

The Leica AT403 Absolute Tracker is a portable coordinate measuring machine (PCMM) that delivers extreme precision over ultra large distances. Its lightweight design and internal batteries allow for complete portability. It is the first tracker ever to have an IP54 rating, which enables it to operate in the most demanding environment and still maintain the highest level of precision. Optional Leica B-Probe handheld point-probing tool is a perfect match for the Leica Absolute Tracker AT403. Uniquely portable and usable the battery-powered cableless operation possibilities of the Leica B-Probe make it a unique proposition in the world of large-volume 3D metrology.

The Perfect Partner for the Leica B-Probe:
The Leica Absolute Tracker AT403 presents the ideal solution for portable probing applications when paired with the established quality of the Leica B-Probe portable probing tool. This single-case portable probing system delivers improvements in measurement process speed and usability as well as customisable hidden-point reach. When added to the already class-leading cableless functionality of the Leica B-Probe, large-volume probing is now simpler and better than ever before.


  • IP54 sealed: Dust and Water proof. Independently certified IEC 60529 usage in even the most demanding conditions.
  • Integrated environmental monitor: Automatic reading and updating of the environmental parameters avoids inaccurate calculations or wrongly input values.
  • 10 Hz Update Dynamic Measurement: For measuring of geometric features like spheres and circles
  • Cable-less design: By combining built in WiFi connectivity and on board battery power, the sensor can operate without any wires connected at all.
  • Hot swappable battery operation: No need to worry about AC (mains) power - the sensor can run continuously with a new set of batteries able to be swapped in without interruption
  • Automatic target recognition (ATR): The ATR allows constant tracking and fine positioning with different reflector types to a typical radial volume of 320 m.
  • PowerLock beam recovery technology: No need to worry about ”breaking the beam”: the tracker automatically locks onto the user providing up to 20% time savings over traditional laser tracker technologies
  • Proven Absolute Distance Meter technology: The most accurate Leica Geosystems distance meter ever: The ADM has a resolution of 0.1 micron and a maximum uncertainty of 10 microns over a full 160 m radial volume.
  • Quick Release tribrach and precision level to gravity sensor: A built in ”survey grade” level to gravity sensor is combined with a simple three screw levelling quick release platform for quick and easy machine setup and relocation.
  • Overview Camera: Integrated Overview Camera to allow on-line steering of the laser tracker for remote or fixed installations
  • Extreme Portability: Extremely light and compact: 8.1 kg incl. controller, just over 290 mm tall Measuring where no other laser tracker can go. The controller stays out of the user's way, e.g. attached to the tripod.
  • Leica Geosystems proprietary quadruple reading absolute angle detection system: The absolute angle encoders provide traceable ISO 17123-3 0.5” accuracy with a 0.07” resolution guaranteeing system accuracy over extremely long ranges.
  • Power Over Ethernet: Due to its low power requirements the sensor can use POE+ technology that combines power and data into a single off the shelf Cat5 LAN cable.
