An optical microscope apparatus includes an illumination optical system for illuminating an observation target object; an observation optical system for introducing an observation image of the observation target object; and an image rotation device provided on a light path common to the illumination optical system and the observation optical system, for rotating the observation image. 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 bean therefrom, and is driven to be rotated around an entering/exiting optical axis, thereby to rotate the observation image. The optical microscope apparatus further includes 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; and a 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 a substantially equal position, with respect to the observation target object, regardless of rotation operation of the image rotation device.

Optical microscope apparatus

Light from a mercury lamp is focused by an objective lens system and is incident on a specimen to be examined. A focusing optical path of light reflected by the specimen is split into an optical path of an ultraviolet ray and an optical path of visible light by a dichroic mirror having wavelength selectivity. The ultraviolet ray is guided to an ultraviolet CCD camera. The ultraviolet CCD camera supplies a monochrome picture signal to a monochrome display through a first picture processor. On the other hand, the visible light is guided to a color CCD camera. The color CCD camera supplies a color picture signal to a color display through a second picture processor. Therefore, an ultraviolet picture of the specimen is displayed on the monochrome display at a high resolving power and a large magnification. At the same time, a color picture of the specimen is displayed on the color display.
