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 at least spanning the longitudinal axis and an angle greater than ninety degrees to the longitudinal axis. The endoscope further includes an imager comprising an imaging surface area that receives at least a portion of endoscopic image transmitted by the wide angle lens system and produces output signals corresponding to the endoscopic image field and image forming circuitry that receives the output signal and produces an image signal.
