摘要：A microscope calibrator (50) includes a housing supporting a series of focussing targets each situated at a predetermined distance from one another. Attributes of the microscope are determined by focussing the microscope on one ore more of the focussing targets and determining a location of the microscope with respect to the focussing targets focussed upon. The position of the focussing targets are determinable by virtue of a local reference frame target (52) attached to the microscope calibrator or by using a tracked probe to communicate the location of each point focussed upon by the microscope on each of the focussing targets.
