Abstract
Abstract An enlarging optical system having an objective lens and an ocular lens is received in a body of a microscope. A beam splitter is received in the body on an optical path of the enlarging optical system. This beam splitter is disposed between the objective lens and the ocular lens. A monitor television is also received in the body. An image obtained by an endoscope is displayed in this monitor television. The image displayed in the monitor television is reflected by the beam splitter toward the ocular lens.
