ABSTRACT:
An illumination optical system for use in an endoscope comprises a glass pane disposed in front of a source of illuminating light and which is centrally defined with a reflecting surface which is inclined with respect to the optical axis of the source. Light passing through the source in alignment with the optical axis thereof illuminates a near object while light passing through the source offset from its optical axis illuminates a far object.
