What is Laser Tracker used for?
Laser trackers are instruments that accurately measure large objects by determining the positions of optical targets held against those objects. The accuracy of laser trackers is of the order of 0.025 mm over a distance of several metres.
How does a laser tracker work?
The operation of a laser tracker is easy to understand: It measures two angles and a distance. The tracker sends a laser beam to a retro-reflective target held against the object to be measured. Light reflected off the target retraces its path, re-entering the tracker at the same position it left.
How much is a laser tracker?
Even with the advanced technology and additional features in the new model, the FARO Laser Tracker X costs $89,900 — which is $35,000 less than the Tracker SI model.
How does laser tracker measure distance?
The tracker sends a laser beam (hence, “Laser Tracker”) to a retroreflective target (commonly a spherically mounted retro reflector, or SMR) that is held against the object being measured. As the light re-enters the tracker, a distance meter in the tracker calculates the distance from the tracker to the retroreflector.
How accurate is the FARO Laser Tracker?
The FARO® Laser Tracker has a level that is accurate to +/- 2 arcseconds. There are 3600 arcseconds in one degree, or 1 arcsecond is 0.000278 degrees. Relatively speaking, that is approximately +/-0.002″ per 17′ from the Tracker head.
What is a FARO Laser Tracker?
FARO® Vantage Laser Trackers enable you to build and inspect products by measuring quickly, simply and precisely with exceptional portability. 6DoF and standard probing are enhanced by FARO ActiveSeek™, a feature to automatically locate and follow the active target.
How much does FARO Arm cost?
The Advantage FaroArm and the FARO Advantage Tracker will be the Company’s most inexpensive CMMs, with prices in the USA starting at only $19,900 and $69,900, respectively.
What is the accuracy of a FARO arm?
Accuracy: ±35µm (±0.0014”) Repeatability: 35µm, 2σ (0.0014”) Stand-off: 80mm (3.15”) Depth of field: 85mm (3.35”) Effective scan width: Near field 53mm (2.09”) Far field 90mm (3.5”) Points per line: 752 points/line Scan rate: 60 frames/second x 752 points/line = 45,120 points/sec.
What kind of device is a laser tracker?
What is Laser Tracker? A laser tracker is a measuring device that projects a laser beam onto an optical target that is in contact with an object to be measured, and determines the three-dimensional position of the target.
What is the accuracy of a laser tracker?
The range of a modern laser tracker is as much as 390′ and in most cases, when working within reasonable range to a measurement, laser trackers are accurate to 0.001”. Like most measurement instruments that measure by accounting for angles, its accuracy diminishes as the distance to the target increases.
Which is the best laser tracker for metrology?
A long-term standard in industrial metrology: Laser Tracker Systems lead the field in terms of the accuracy, reliability and durability of portable coordinate measuring machines. Real-time asset management for portable and automated metrology Leica Absolute Tracker AT960.
Can a touch probe be used with a laser tracker?
When a measurement point is beyond the line-of-sight of the laser tracker, an extendable touch probe is the natural solution for fast and easy hidden-point measurement. Our laser tracker-based robotic measurement and control systems are about elevating the potential of industrial automation and bringing metrology-grade accuracy to the…
