  • Confocal scanning microscope
    Patent number: 7190514
    Abstract: The present invention provides a confocal scanning microscope whereby fluorescence observations can be made using a plurality of types of excitation light without the need for attaching and detaching a light source to and from the optical fiber. The confocal scanning microscope comprises: a light source unit for emitting excitation light that excites a sample; a scanner unit for scanning the sample with the excitation light; and an imaging camera for capturing an image of the sample by receiving fluorescent light emitted from the sample; the light source unit having a plurality of light sources for emitting laser light with different wavelengths and a multicore optical fiber cable for transmitting light from the plurality of light sources, one end of the multicore optical fiber cable being separated into a plurality of optical fibers, and light from each of the plurality of light sources being input to one end of each of the separate optical fibers.
    Type: Grant

  • Optical image separation system and confocal scanning unit
    Patent number: 6631029
    Abstract: An optical image separation system, connected to a confocal image output port of a Nipkow disk type confocal scanner, wherein light returned from a sample and emitted from the confocal image output port is separated into a plurality of different wavelen regions, respectively, so that a plurality of samples emitting different wavelenghts are concurrently detected.
