Abstract:
A slit 9 having a predetermined length is formed in a mirror 8 and an illumination light L of illumination part 10 irradiates an observation area E in a manner of zero-angle illumination to an optical axis K. The illumination part is movable to form an oblique path of the illumination light L which passes through the slit 9. A shadow appears due to the oblique path of the illumination light L and it facilitates a stereoscopic observation.
