Abstract
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.
