Abstract:
A reflected fluorescence microscope for allowing a plurality of reflected illumination light beams to be selectively irradiated onto a sample, to carry out optical operations of said sample and its fluorescence observation simultaneously, said microscope comprising:a first reflected illumination optical system light path provided in a direction which crosses an observation optical system light path to said sample at a point of intersection;a second reflected illumination optical system light path provided in a direction which crosses said observation optical system light path at the same point of intersection as that between said observation optical system light path and said first reflected illumination optical system light path;a first movable member having a cube including a first dichroic mirror and a cube including a second dichroic mirror, for providing a desired one of said cubes to be inserted or detached at said point of intersection between said observation optical system light path and said first or second reflected illumination optical system light path;a third reflected illumination optical system light path provided in a direction which crosses said observation optical system light path at a different point of intersection from that between said first or second reflected illumination optical system light path; anda second movable member having a cube including a third dichroic mirror, for providing said cube with said third dichroic mirror to be inserted or detached at said point of intersection between said observation optical system light path and said third reflected illumination optical system light path,wherein said first dichroic mirror reflects the light from said first reflected illumination optical system light path to a side of said sample, while transmitting fluorescence emitted from said sample.
