Leica Absolute Tracker AT403 

The Leica Absolute Tracker AT403 is a portable coordinate measuring machine (PCMM) that delivers extreme precision over ultra large distances.

An all-in-one metrology solution more portable than any other on the market, the Leica Absolute Tracker AT403 from Hexagon Manufacturing Intelligence is a self-contained measurement workshop inside a compact and convenient single case.

With outperforming measurement process speed, operational simplicity like no other laser tracker and an unmatched level of robust construction, the Leica Absolute Tracker AT403 is a calculated bundle of affordable innovation without equal on the portable measurement market.

Improvements include faster and more economical stationary and continuous measurement processes, along with a streamlined station change procedure. Added WiFi access point functionality and hot-swappable batteries deliver unmatched measurement freedom. Designed for leading results in almost any imaginable measurement environment, it is rated for operation in temperatures ranging from -15 to 45 degrees Celsius and features built-in environmental monitoring, orient-to-gravity functionality and construction in line with the rigorous IP54 certification standard.

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.
