1. An optical-scanning examination apparatus comprising:

  • a light source unit;

    a focusing lens for forming a first intermediate image of excitation light emitted from the light source unit;

    an imaging lens for focusing the first intermediate image;

    a first objective lens for forming a second intermediate image of the excitation light focused by the imaging lens;

    an optical fiber bundle one end face of which is disposed near the second intermediate image position;

    a second objective lens, disposed at the other end face of the optical fiber bundle, for imaging light emitted from the other end face of the optical fiber bundle onto a specimen;

    an imaging unit for imaging return light that returns via the second objective lens, the optical fiber bundle, the first objective lens, and the imaging lens; and

    a scanning mirror device, disposed at the first intermediate image position, the scanning mirror device being formed of a plurality of mirrors that simultaneously receive the first intermediate image and that can be selectively turned on and off.
