  • Patent number: 10054781
    Abstract: A microscope apparatus includes a detection optical system that detects fluorescence produced in a specimen immersed in a medium having a different refractive index from air and accommodated in a container and acquires a fluorescence image. An illumination device focuses excitation light emitted from an excitation-light source, in the form of a plane along a plane intersecting an optical axis of the detection optical system and makes the planar excitation light incident on the specimen in the container. A driving unit moves the specimen in a direction of an optical axis of a cylindrical lens. An illumination control unit adjusts a focal position of the illumination device based on a movement amount of the specimen moved by the driving unit such that an air-equivalent length along an optical path of the excitation light from the illumination device to the optical axis of the detection optical system remains constant.

  • 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.
