When exchanging a dichroic mirror to detect fluorescence of a different wavelength, it is unnecessary to carry out precise positional adjustment, particularly in a compact examination apparatus, and the dichroic mirror can be easily exchanged. The invention provides a connection unit including a light-source optical fiber, removably connected to the light source, for conveying the excitation light from the light source; a collimator lens for collimating the excitation light emitted from the light-source optical fiber to introduce the excitation light to the optical scanning section; and a dichroic mirror for splitting off fluorescence, which is generated in the sample and which returns via the objective lens and the optical scanning section, from a light path of the excitation light and for directing the fluorescence to a photodetector. The light-source optical fiber, the collimator lens, and the dichroic mirror are secured to each other such that optical axes thereof are aligned.
A connection unit which is removably attached to an apparatus main body including an optical scanning section for scanning excitation light from a light source and an objective lens for imaging the excitation light scanned by the optical scanning section onto a specimen, the connection unit comprising:
