    摘要: An epidark illumination system for use with a microscope in which a sample is illuminated from around an objective by a ring-shaped light flux having its center coincident with the optic axis of the objective to enable the sample to be observed in a dark field of view comprises a ring-shaped condenser lens member disposed adjacent to the forward end of the objective with the center of the lens member being coincident with the optic axis of the objective to condense the light flux upon the sample, and a scattering member for scattering the ring-shaped light flux disposed in the light path before the ring-shaped light flux reaches the ring-shaped condenser lens member.

    摘要: Disclosed is a horizontal position detecting device for maintaining the surface of a body to be inspected vertically to the optical axis of a main objective lens. The device includes an illumination optical system and a condenser lens system. The illumination optical system supplies parallel light rays to the surface of the body from the direction oblique to the optical axis of the objective lens. The condenser lens system condenses the light rays supplied by the illumination optical system and reflected by the surface of the body. The optical axes of the illumination optical system and the condenser lens system are arranged substantially symmetrically with respect to the axis of the objective lens.
