3D range
The Leica Absolute Tracker AT960 is a robust, all-in-one laser tracker that fits in a single flight case.
Offering high-speed dynamic measurement as standard, it is a complete solution for six degrees of freedom (6DoF) probing, scanning and automated inspection as well as reflector measurement.
Absolute distance meter
The foundation of laser tracker distance measurement delivers highly accurate 3D measurements over distances of up to 160 metres.
Absolute Interferometer
The IFM and ADM core technologies have been used for more than a decade in our laser trackers around the world. These core technologies have been improved and combined to create what we is now called the “Absolute Interferometer” or AIFM, and represent the most accurate and stable dynamic distancing unit that we have ever created. The AIFM truly changes the way that laser trackers are used. The AIFM combines the best of both worlds.
The original laser tracker capability, 3D measurement is still a vital component of the tracker toolkit. By identifying your point of measurement with a specialised retroreflector, its precise geometry can be recorded in seconds. With a 3D laser tracker, high-accuracy inspection and alignment tasks can be performed over ultra-large measurement volumes of up to 320 metres in diameter.
A 3D laser tracker equipped with an automatic target-lock function like PowerLock can reduce measurement process times by as much as 30 percent by detecting reflector targets within the tracker’s field of view with no need for operator intervention – particularly useful after line-of-sight is broken, as can happen often within a busy work environment.
Extending the measurement capability of a laser tracker is possible with advanced 6DoF (six degrees of freedom) technology. By introducing an independent sensor with a constellation of LED targets, the tracker can calculate not just position but orientation. This allows for the accurate calculation of the 3D location of points offset from the main point of measurement.
The scanner digitises a part by projecting a laser onto it, and then detecting and analysing the properties of the light reflected back. This information as interpreted as millions of individual data points that together represent the geometry of the scanned surface and features.
Laser scanning in an industrial metrology context can be used for several distinct purposes, which fall within two broad categories.
Improved productivity
Hidden-point capability allows the measurement of hidden areas without relocation of the laser tracker, with the potential to reduce measurement time by up to 80 percent compared to reflector measurement.
Error-free measurement
When measuring parts using reflectors mounted on holders, it’s necessary to manually compensate the offset, a stepthat is too often overlooked and a common cause of inaccurate results. The T-Probe eliminates this problem with its faultless automatic stylus recognition.
Designed to slip seamlessly into the production process, whether in the quality room or inline, manually operated or robot-mounted and fully automatic.
• All-in-one integrated design.
• Built-in WiFi with true access point functionality.
• Batteries compliant to IATA regulations.
• Independent hot-swappable battery power supply.
• Convenient flight cases for simple transportation.
Industrial automation is long-established as the future of manufacturing. Metrology-enhanced automation is the key to that future. By making automated inspection and production independent of unreliable robot accuracy, metrology tools like laser trackers combine the fine attention-to-detail of manual production with the unbeatable productivity benefits of automated setups.
Inspection and validation
The 3D point cloud created by a laser scanning system can be used for dimensional inspection or GD&T, with the results being compared against nominal CAD values. Large point clouds can be overlaid on a CAD model for fast visual inspection of deviations.
Reverse engineering
It can be useful to take an existing physical part, measure it to determine its characteristics and then process the data to create a CAD model. This method is often used in cases where the product design process involves significant manual operation, such as in automotive design.
The Leica T-Probe is a completely wireless solution for probing hidden or hard-to-reach points. It combines minimal setup times, quick station changes, and a high point-acquisition rate with automatic stylus recognition and multi-function buttons for maximum productivity. This ergonomic device ensures fast, single-point data acquisition without cables or external power sources.
Used with the Leica Absolute Tracker AT960, the T-Probe provides a flexible, top-performance probing system with up to 30 meters of range. Small, light, and battery-powered, it delivers the highest accuracy among handheld probes while offering more than six degrees of freedom. Its user-friendly design helps streamline measurement processes for a wide range of professional applications.
