The XL-80 interferometer from Renishaw Inc. is lighter and more portable than its predecessors, making it simpler for quality control and maintenance technicians to calibrate manufacturing and laboratory equipment. The instrument can measure distances as long as 260 ft, yet it still provides measurement speeds of up to four meters per second.
Both speed and accuracy have been upgraded substantially. It runs at 50 kHz, compared to only 5 kHz for Renishaw units that are now in the field. Resolution is 1 nanometer, while accuracy is 0.5 ppm, substantially better than its predecessor's 0.7 ppm. Weight including cables, power supplies and sensors is under seven lbs. The unit can employ optics from previous generation hardware, helping keep costs down.
