20090116102 | Stereomicroscope - An illumination optical system projects an illumination light onto an observation object via an objective lens. A first observation optical system guides the illumination light reflected by the observation object to a first ocular lens. A second observation optical system includes a second ocular lens for observing the reflected light of the illumination light. An optical system drive mechanism rotates the second observation optical system and arranges the second observation optical system between a first position and second position facing each other. A reflecting member is disposed at a position retracted from the illumination light path and the reflected light path and reflects the reflected light in a direction different from the optical axis. A drive mechanism rotates the reflecting member around a rotation axis orthogonal to the optical axis and guides the reflected light to the second observation optical system arranged at the first or second position. | 05-07-2009 |

20160116726 | THREE-DIMENSIONAL STEREOSCOPIC MICROSCOPE - An apparatus for forming stereo image pairs comprises a set of perspective apertures within a perspective aperture plate, separated within a stereoscopic horizon by an inter-aperture distance. An offset aperture is disposed inside an illuminator of the apparatus. The offset aperture is positioned to form a cone of illumination that is mirror symmetrical with respect to the two perspective apertures. The perspective apertures are adjustable both in size and in their position within the aperture plate in order to position them with respect to a cone of light produced at the perspective aperture plate. The offset aperture is similarly adjustable in size and position. The arrangement ensures that light illuminating an object viewed using the apparatus has a narrow cone of direction and angle of incidence, which ameliorates negative effects that occur in stereoscopic systems with objective lens systems having large numerical apertures. | 04-28-2016 |
