Leica Absolute Tracker AT401Absolutely portable»The Leica Absolute Tracker AT401 is aportable coordinate measuring machine(CMM) that allows extreme precisionover ultra large distances. It is able to bepowered by its own internal battery andis able to work in the most demandingenvironment, yet maintains the highestlevel of precision and the largest ever workenvelope. The Leica Absolute Tracker AT401has a unique “All in One” system designthat incorporates such needed accessoriesas built in live video, level to gravity,environmental monitoring and even anintegrated IR remote control. By utilizingthe integrated Wireless LAN communicationthe sensor can be used completelywirelessly making this the most portableAbsolute Tracker ever.

Measure where no otherCMM can go»

Especially large structures require highlyaccurate, flexible and portable metrologyequipment. This surrounding is right forthe Leica Absolute Tracker AT401.It redefineslarge scale portable measurementand opens the door for unprecedentedmetrology applications.A new level of portability & durabilityThe complete measurement system weighsless than 15 kg including the case and ina minimum configuration it will fit into theoverhead compartment of most commercialairliners. This is truly the world’s mostportable CMM

Mastering anyindustry conditionReady for any environmentUtilizing a completely sealed design that isindependently IP54 (IEC 60529) certifiedmeans this sensor can be installed in themost unforgiving environments. Sprayingcoolant, dust, weld splash, nothing is tooharsh for this sensor. The Leica AbsoluteTracker AT401 is the first laser tracker certifiedfor outdoor use, even in the rain.

PowerLockPowerLockLeica Geosystems introduced the world toPowerLock in 2009. This vision technologydetects a reflector and automatically locksthe laser beam onto it, even when the targetis moving. The laser beam moves to the user,not the other way around. In the past operatinga laser tracker was almost a “black art”.It took time and experience for an operator tolearn how to efficiently use the sensor withoutbreaking the beam. PowerLock changedthis completely and makes the handling of alaser tracker much easier.

»A wireless all-in-onelaser trackerCable-less operationWith two identical batteries – one in the sensor,one in the controller- the Leica AbsoluteTracker AT401 can run for a work day. Whenpower approaches a critical level, the batteriescan be either replaced or hot swapped.The laser tracker continues running as ifnothing had happened. With the built in WiFiconnection the Leica Absolute Tracker AT401becomes a completely wireless portableCMM free from any external data or powercable requirements.Optionally the Leica Absolute Tracker AT401is ready for Power over Ethernet. With thistechnology, a regular LAN cable supplies thesensor with both data and power.Ultra Large Volume MeasurementsWith endless telescope rotation the sensorcan measure a full 360° horizon and a 290°vertical dome. Pair this with a typical radialvolume of 320 meters and you have theworlds largest volume precision CMM.Complete system integrationThe Leica Absolute Tracker AT401 is readyfor any measurement task that comes itsway. All accessories such as remote control,environmental monitor or level sensor arealready built in.

Boundaries are thereto crossAerospaceThe Leica Absolute Tracker AT401’s portability andcapability for one man operation make many challengingaerospace applications such as tool buildingand inspection, geometry check, part alignment,metrology assisted assembly or antenna constructionmuch easier.Off highway and heavy vehiclesManufacturing vehicles of any type requires metrologyequipment which helps to ensure top quality. Toolrepeatability, vehicle inspection, line installation orline maintenance are just a few examples where theLeica Absolute Tracker AT401 excels. With an ultralarge volume measurement and wireless operationthese tasks can be completed easier than ever before.Power GenerationTurbines and generators for use in wind or waterpower must withstand extreme conditions. Forchecking strict tolerances, ultra high accuracyis essential. The Leica Absolute Tracker AT401’sportability and flexibility make large-volume shaftor machine alignment, machine inspection or blademeasurement easy.Research and scienceWhen large structures and distances are the object ofscientific activities, the Leica Absolute Tracker AT401with a typical radial volume of 320 m is the rightmetrology tool. Ring survey or part inspections on anaccelerator are just two examples.ShipbuildingDue to its infinite rotation and extreme measurementrange, the Leica Absolute Tracker AT401 can handleeven the ship building industry’s gigantic dimensionswhen it comes to surveying, aligning engines andshafts or installing equipment.

Expertise in qualityIt all started with a theodolite. When Jakob Kernfirst constructed precision instruments in Switzerlandof the 1830s, industry was in its early stages.But there is one lasting legacy – the commitmentto absolute quality. Many Leica Geosystems instrumentsare still in daily use after several decades,as for example the first ever built Leica Geosystemslaser trackers from 1990. Today, the LeicaGeosystems metrology branch is a part ofthe global Hexagon Metrology network.Where quality comes togetherEvery installed system is the result of individualconsulting from a Hexagon Metrology sales engineeror a certified dealer. The definition of the metrologychallenge is the initial step. Together withthe future users, Hexagon Metrology develops theperfect package consisting of a Leica Geosystemssensor, suitable software and optional systemextensions. After the purchase, HexagonMetrology offers customized service andsupport for the entire instrument life.
