The FLS-C from Dimetix AG, Herisau, Switzerland, is a laser distance sensor that measures absolute distances up to 500 m without contact. Absolute accuracy is 1 mm and repeatability is typically 0.3 mm. The optical device measures distances on natural and reflective surfaces and in hostile environments, determining the position of objects that are either difficult to access or may have high surface temperatures. The IP65-rated device has a solid metal case and is suited for use in the automotive, paper, metal, and textile industries.
