Abstract

PURPOSE:To attain image-pickup with lighting suitable for the kind of observation and an observed object by installing a lens for irradiating a wide area and a lens for irradiating a narrow area on the tip of a scope and irradiating an object through plural irradiating lenses in responding to various kinds of requests of irradiation. CONSTITUTION:Irradiating light emitted from the light source part of an endoscope and guided from an end surface 13 on the light source side by a light guide 7 is divided into two groups at the tip of the scope. The guide 7 forks into two on the tip 12 side of the scope and is positioned and fixed by a supporting body 12D. A cap 12C on the leading edge of the scope supports and fixes a wide visual field lens 12A and a narrow visual field lens 12B, which are disposed on forked tip parts of the guide 7. The irradiation is simultaneously executed from the lenses 12A and 12B. The lens 12A irradiates all the area of a visual field so as to brighten a peripheral part. And the lens 12B irradiates the part near the center of the visual field, so that the irradiating light in response to the requests at the time of observation can be obtd.
