The word “LASER” in the laser distance sensor means Light Amplification of Stimulated Emission of Radiation. Laser distance sensors are mainly used for distance measurements without physical intervention. Laser sensors are mainly used for positioning and type classification in machine building and handling equipment. Laser sensors can give precise and accurate measurement of distance on any surface. Laser sensors are applicable in various sectors such as Medical, metrology, electronics, glass industry, metals, foundries, automobile manufacturing, optical system, semiconductors, plastic industry, scientific research, aerospace, food industries, etc.
