Topcon has announced the release of three new models in their GLS line of scanners. The GLS-2000S is rated for short-range applications, at distances of up to 130m. The GLS-2000M is rated for mid-range applications, up to 350m. The GLS-2000L is rated for for (you guessed it), long-range applications up to 500m.
The scanners are designed using Topcon’s Precise Scan Technology II, which Topcon says can emit pulses up to 3 times faster than previous GLS scanners. As VP of the Topcon GeoPositioning Solutions Group Charles Rihner explained in a prepared statement, “Using faster pulse signals enables timing to be detected more precisely, which results in reduced noise and higher-accuracy data.”
Each scanner includes two 5 megapixel cameras, one equipped with a 170-degree wide-angle lens for high-speed imaging, and the other with 8.9-degree telephoto lens that is aligned with the measuring axis. The scanner quickly switches focal length settings depending on the scan.
The GLS scanners also allow for the user to select either a Class 3R laser or a Class 1 laser for scanning, depending on the job at hand.
