PURPOSE: To make it possible to obtain a full illumination capable of putting both a surgeon and a recorder into the visual field by providing the system with a given housing, a magnifier assembly capable of reciprocating movement, an optical prism at one end of a communication route, and an adjustable iris. CONSTITUTION: The light comes into an adapter 66 via a fiber cable 40, then, passes through there, and advances into a controllable lens unit 41 mounted in a recess 64 and formed into a desired circle to cover the light into a visual field 31. The light from the recess 64 is sent to a right-angle prism 25, then sent up to the visual field 31 to observe the object by the surgeon eyes 33 via an objective lens 22 or a binocular 20. The light from the visual field returns back to a microscope via the objective lens 22, keeping the full illumination capable of being used from a light source 40 up to the binocular 20, while the full illumination is sent backward up to the image communication route 72 of a module 53 via the right-angle prism 25. This can obtain the full illumination capable of being used in the visual field by the surgeon and recorder. |
