On the other hand, at the time of fluorescent observation, a barrier filter 28 is inserted into an observation optical path, and also, a mirror 37 is inserted into a regular illumination optical path. Therefore, an excitation illuminating light from an Hg-Xe lamp 33 passes through an excitation illuminating optical system 30b, the reflecting prism 12 and the objective lens 21, and irradiates the surgical operation object part S. In such a way, a fluorescent substance of the surgical operation object part S is excited, and by observing its fluorescence through the barrier filter 28, the operator can execute the fluorescent observation of high contrast.
