鏡用架台。[Scope of Claim for Utility Model Registration] A microscope mount configured to switch between a dark field illumination method and a bright field illumination method by moving a switching member relative to the mount body, wherein the switching member includes a switch for the dark field illumination method. A dark-field optical member and a bright-field optical member for bright-field illumination are arranged side by side, and the movement of the switching member causes the dark-field optical member and the bright-field optical member to be included in the illumination light flux from the illumination light source. A microscope mount characterized by being selectively inserted and removed.
