The Leica Absolute Tracker AT402 Laser Tracker is Hexagon Metrology’s most portable 3D Absolute Tracker, it combines portability with superior precision.

The At402 has a small footprint with the largest ever work envelope. It can be powered by its own battery (which has an extended battery life), has a rugged design and can be wirelessly operated using its integrated WiFi access point functionality. This allows it to go virtually anywhere and probe hard-to-reach points that are outside the field of view of a laser tracker with a reflector ball. 

Hexagon Metrology released the Leica Absolute Tracker AT402, the next-generation laser tracker based on the Leica AT401 product line. The portable 3D Absolute Tracker can be utilized for fully guided 3D measurement processes, as well as traditional inspection tasks. The new laser tracking system is optimized for ease of use, so operators can focus on the measurement task instead of complicated settings, such as the number of samples or measurement frequency. The Leica AT402 is reportedly ideal for large volume, precision measurement applications performed by industries such aerospace, power generation, heavy equipment and other manufacturers that produce large components and assemblies.

Leica AT402 Absolute Laser Trackers are portable coordinate measuring machine (CMM) capable of taking large volume measurements in 3D or with 6DOF to sub millimetre accuracies.

The Leica AT402 introduces a simplified user interface with four pre-defined measurement profiles that adjust the instrument settings to any measurement condition with the click of a button. In addition to its standard mode streamlined for daily operation, users can easily change settings for outdoor measurement jobs and for applications requiring exceptional speed or accuracy. The laser tracker's all-in-one design integrates other usability features, such as IR remote control, environmental monitoring, level to gravity, in addition to powerful standard features such as Leica PowerLock technology, a certified-IP54 rating and built-in WiFi connection for wireless operation.

The Leica Absolute Tracker AT402 is the most portable 3D Absolute Tracker for traditional inspection tasks or for fully guided measurement processes. It is able to be powered by its own internal battery and is able to work in the most demanding environment, yet maintains the highest level of precision and the largest ever work envelope. The AT402 features increased ruggedness and extended battery life. The Leica Absolute Tracker AT402 has a unique “All in One” system design that incorporates such needed accessories as built-in live video, level to gravity, environmental monitoring and even an integrated IR remote control. By utilizing the integrated WiFi access point functionality the sensor can be used completely wirelessly.


Features and benefits of Absolute Laser Tracker - Leica AT402:

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.
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.
