Perceptron ScanR Green Laser Line Scanner for Highly-Reflective Materials The ScanR is the world's first green laser for use with portable and fixed CMM machines. It represents the 6th generation of CMM-laser scanners from Perceptron, dramatically extending the range of engineering materials that can be laser-scanned. It offers a significant customer advantage over red and blue laser scanners when scanning highly reflective and carbon fiber materials.
