Microscope having an illumination optical system which is integrated with the microscope base which reduces heat conduction from the microscope base to the microscope frame

摘要

A base, a frame, and an arm which constitute a microscope body are formed independently of one another, and receptacles receiving fastening members at the bottom of the frame are formed as protrusions so that the area of contact between the base and the frame is smaller than a predetermined area. The protrusions are formed so that they surround the fastening members. The protrusions increase resistance to heat conduction from the base to the frame to reduce the amount of heat which is generated from the lamp and conducted from the base to the frame. Such an arrangement reduces an image blur due to thermal deformation, thereby providing a good specimen image.
