  • Patent number: 9766444
    Abstract: A digital microscope (1) includes an optical fiber bundle (17) that supplies bright field light, an optical fiber bundle (18) that supplies dark field light, an optical fiber bundle (19) for causing light from a light source to enter the optical fiber bundle (17) (18) and a mechanism for changing a mixture ratio of the bright field light and the dark field light according to operation in an operating section (26). A light entry end of the optical fiber bundle (17) and a light entry end of the optical fiber bundle (18) are arranged adjacent to each other to face in the same direction. A light exit end of the optical fiber (19) is arranged to be opposed to both of the light entry ends.

  • Patent number: 7491921
    Abstract: An apparatus for efficiently observing protein crystals for use in X-ray analysis is provided. This apparatus includes an ultra-compact proximity imaging unit and a three-dimensional observation adaptor (4) attached thereto. The imaging unit includes a CCD camera (2) and a lens system (3) and an illumination system in front of the CCD camera (2). The lens system (3) includes a variable or fixed magnification lens. The three-dimensional observation adaptor (4) has an optical-axis reflective surface (4c) disposed between the frontmost lens of the lens system (3) and a production container (100) containing protein crystals in the optical axis a of the lens system (3) and a revolving reflective surface (4d) disposed opposite the optical-axis reflective surface (4c) revolvably about the optical axis to three-dimensionally observe the crystals contained in the production container (100) in an oblique or lateral direction.

  • Patent number: 6522466
    Abstract: An apparatus for an object in an ultramicropore space has a lens system so that an incidence point P with the diameter in a range from 0.3 to 0.7 mm comes to a position in a range of 12 to 17 mm away from the front side of an object lens 30. At the same time a reflection mirror 15 is positioned with a reflection mirror mounting member 8 formed with the V-shaped form in front of the object lens 30 and a reflection mirror holding frame 8 at the position of the incidence point. This arrangement is useful fir example to observe a soldered section 52 of an IC chip 50 by inserting this reflection mirror 15 into the ultramicropore space.
