Abstract
An optical system is disclosed for an endoscope having a generally tubular distal end in which an objective lens assembly and a solid-state video camera are internally housed so that an image formed by the lens assembly is focussed upon the video camera. The video camera is disposed along or in proximity to the center axis of the distal end of the endoscope. The video camera may be positioned in this way due to the provision of a reflecting surface which is angularly disposed in opposing relationship with an input surface of the video camera, and deflection means disposed in front of the lens assembly and within the objective lens assembly, or between the lens assembly and the reflecting surface, so that an image formed by the lens assembly can be focussed on the input surface of the video camera.
