  • Patent number: 9710738
    Abstract: A cell counting device for counting the number of cells in a sample includes: an accommodation portion that accommodates, in a removable manner, at least a part of a holding member for holding the sample; and a display unit configured to display information including a result of counting of the number of cells. The display unit has a screen inclined with respect to a bottom of the cell counting device. The bottom is configured to be in contact with a placement surface on which the cell counting device is placed. The display unit is provided between the accommodation portion and the bottom.

  • Patent number: 9019600
    Abstract: A microscope system includes a microscope body having a base portion forming a foundation, an arm portion extending substantially parallel to a bottom surface of the base portion, and a frame portion connecting ends of the base portion and the arm portion, having substantially a C shape in side view and holding an illumination optical system ejecting illumination light from a light source to a specimen. A light source unit is connected with the microscope body and radiates illumination light to the illumination optical system. A focusing unit supports a stage for placing the specimen and at least holding an objective lens focusing the specimen by collecting observation light from the specimen on the stage. The microscope body and the focusing unit do not contact each other in a state where an optical axis of the objective lens coincides with an optical axis of the illumination light.

  • Publication number: 20100277794
    Abstract: A microscope includes a wire grid polarizing beam splitter that reflects a light emitted from a light source to a direction of an observation optical axis to cause the light to enter an objective lens, and transmits a reflected light from a specimen to cause the reflected light to enter an imaging lens; and a quarter wavelength plate that is placed between the objective lens and the specimen.

  • Patent number: 7436524
    Abstract: The present invention has a three-dimensional apparatus including a lattice pattern placed in an optical path and having a slit-like light transmitting portion formed of pitches set at fixed intervals, and a projecting optical system that projects a lattice pattern image formed by the lattice pattern on the sample so that the image is inclined at a predetermined angle. A lattice pitch is determined on the basis of set parameters including the magnification of an observing system. A pattern is formed by the lattice pitch. The pattern is used to pick up a deformed lattice pattern image using a TV camera. An image of each position is acquired while shifting the lattice pattern over several levels. A phase is determined. A height is then determined using the difference between the phase and a basic phase corresponding to a pre-provided magnification or the like. The height is then displayed.

  • Patent number: 5303082
    Abstract: A stereomicroscope comprising a pair of observation systems each comprising an objective lens and an eyepiece lens, a pair of light sources disposed above the objective lens for emitting a pair of light beams through a pair of beam splitters into the observation systems coaxially therewith, pairs of polarizers disposed on the side of the eyepiece lenses and the side of the light sources respectively so as to have polarizing surfaces perpendicular to each other, a quarter wavelength plate interposed between the objective lens and a sample to be observed, and a pair of light beam deflecting members disposed between the beam splitters and the objective lens.
