    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.

    摘要： The invention is directed to correcting compound lens forms for 3rd and 5th order ray aberrations. All lens design forms have limiting aberrations. The proposed classes of lenses can be corrected for all 3rd and 5th order ray aberrations. The limiting aberrations are seventh order or higher. A variety of these lenses are disclosed here for the sake of example. These lens design forms can be used in various applications including the objective lens for an endoscope or other optical instrument.

    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.
