Abstract: The present invention relates to a confocal microscope and a measuring method by the confocal microscope in which one or a plurality of measuring units to detect a movement amount are disposed facing a Z-stage having a sample laid thereon, the measuring unit detects a relative position between a condensing position of an objective lens and the sample, a maximum value of a change curved line indicated by light intensity information, and a relative position giving this value are estimated based on obtained relative position information, and a plurality of pieces of light intensity information including the maximum light intensity value of the light intensity, and a confocal image is produced using the estimated maximum value of the light intensity and the relative position as reflection luminance information and height information.

Abstract: 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.

Abstract: 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.
