The SpaceTrac Series, a laser tracking system, is the coordinate measuring machine for large structures. It is active in a wide variety of measuring situations, for example, measurement of large structures such as aircraft, positioning of conveyor lines and machines, measurement of medical instrument movements, emits a laser beam from a measuring head to a Spherically Mounted Retroreflector (SMR) to accurately determine the workpiece coordinates (X, Y, Z) from the reflected beam. This is a multi-functional coordinate measuring machine representing a new standard, demonstrating high accuracy and reliability in a portable compact package.
