  • Imaging device

    Patent number: 7860383

    Abstract: An imaging device includes an axial-direction moving member which moves between an operating position and a retracted position in an optical axis direction, an in-plane moving optical element movable in a plane orthogonal to the optical axis, a controller which moves the in-plane moving optical element in the orthogonal plane to a reference position when the image device changes from the operating state to the retracted state, and a mechanical guide device, provided between the axial-direction moving member and the in-plane moving optical element. In a state where the in-plane moving optical element is deviated from the reference position, the mechanical guide device guides the in-plane moving optical element to the reference position by using a moving force of the axial-direction moving member when the axial-direction moving member moves from the operating position to the retracted position.

  • Polarized total internal reflection illumination optical system by rotary annulus light

    Patent number: 7486440

    Abstract: An illumination system uses rotatable, polarized illumination optics to detect the direction of highly efficient excitation of fluorescent dyes coupled to a sample, or the absorption transition moment, using information on the direction of maximal fluorescence intensity, in which it is possible to detect individual dynamic changes in the internal structure or orientation of an entire protein molecule by coupling a single fluorescent dye molecule to the protein molecule. The polarized total internal reflection illumination optical system by rotary annulus light is also an illumination optical system in which laser beams are introduced into the objective lens of a microscope at the peripheral region by means of the rotatable illumination direction of the laser beams, and is designed to illuminate by the evanescent field that contains only transverse components that are perpendicular to the direction of radiation from the optical axis of the objective lens.
