摘要： An endoscope with a wide angle lens that comprises an optical axis that is angularly offset from a longitudinal axis of the endoscope such that the optical axis resides at an angle greater than zero degrees to the longitudinal axis. The wide angle lens system simultaneously gathers an endoscopic image field, the endoscopic image field at least spanning the longitudinal axis and an angle greater than ninety degrees to the longitudinal axis. The endoscope includes a transmission system with a lens system having f-sin(theta) distortion or substantially f-sin(theta) distortion that distributes the angle of incidence of the light rays gathered from the endoscopic field of view on to the image surface area in order to even out the information density across the surface area of the imager.

摘要： A illumination system for variable direction of view instruments is disclosed generally comprising an endoscope having a longitudinal axis and a variable view vector that pivots about a pivot axis angularly offset from the longitudinal axis. The view vector has an attendant viewing field that travels along a path as the view vector pivots, defining a viewing range. A source of illumination is arranged in a plane offset from the plane in which the view vector pivots and provides an annular, solid angle of illumination that covers the viewing range. In certain embodiments, the pivot axis is perpendicular to the longitudinal axis and the illumination plane is parallel to the pivot plane. In some embodiments, the source of illumination is a plurality of light emitting diodes arranged around the pivot axis.
