A multi-range non-contact probe is provided which performs approximate range-finding measurement functions in addition to more precise structured light measurement functions. The probe is compatible with a probe control interface which allows advanced measuring capabilities and functions to be used with a probe head system that provides a limited number of wired connections. A laser beam of the probe is directed along a first optical path during a first period for providing structured light measurement functions and is directed along a second optical path for a second time period for providing range finding functions. A single beam modification element having at least first and second portions with different types of optical characteristics is moved to output the laser beam from the first portion along the first optical path and then to output the laser beam from the second portion along the second optical path.
