Abstract:
An optical microscope apparatus comprising:an illumination optical system for illuminating an observation target object;an observation optical system for introducing an observation image of the observation target object; andan image rotation device provided on a light path common to the illumination optical system and the observation optical system, for rotating the observation image, wherein the image rotation device is arranged so as to reflect a light beam entering thereinto, for odd-numbered times and to thereafter emit the light beam therefrom, and is driven to be rotated around an entering/exiting optical axis, thereby to rotate the observation image,a scanning optical system provided in the illumination optical system for deflecting observation light to be irradiated on the observation target object, within a predetermined angle range, so as to enter into the image rotation device, so that the sample is scanned with the observation light, anda control device for controlling a deflection angle of the scanning optical system, based on a rotation amount of the image rotation device, such that a scanning range of the observation light is adjusted to be within a predetermined range, with respect to the observation target object, regardless of the rotation operation of the image rotation device.
