Leica Absolute AT403 

The Leica AT402 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.





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.
