Patent ID: 7102815

Claim:
An optical microscope system, comprising: an object lens which collects light from a sample; a capture unit which obtains an image of the sample by capturing light from the object lens via an imaging lens; a removable optical element provided in an infinity correction optical system between the object lens and the imaging lens; a detection unit which detects first location information indicating a location of a predetermined point in the image captured by the capture unit through the optical element, and second location information indicating a location of a point corresponding to the predetermined point in an image captured without the optical element; a calculation unit which calculates a relative amount of displacement between the location indicated by the first location information and the location indicated by the second location information detected by the detection unit; and a movement control unit which moves the capture unit at least in a direction substantially perpendicular to an optical path of light input to the capture unit, so as to match the location indicated by the first location information with the location indicated by the second location information based on the amount of the displacement calculated by the calculation unit.
