An inspection system for performing a test selected from the group consisting of field of view, angle of view, distortion, image quality, depth of field, illumination system transmission efficiency, illumination profile, relative transmission of imaging system and centering error of a rigid, rod lens endoscope. The inspection system includes a testing station supporting a plurality of targets for measuring an optical performance of the endoscope, and a controller controllably displacing the testing station linearly toward and away from the endoscope and rotating the testing station at a nominal angle of view of the endoscope about a first axis and rotating the targets about a second axis parallel to the first axis to selectively displace each of the targets into the field of view of the endoscope.

An apparatus for evaluating performance of a test endoscope includes a plurality of light sources, each generating a respective beam of light which is transmitted through the test endoscope. The apparatus further has a grid formed with a plurality of evenly spaced and uniformly sized pinholes intercepting a beam of light. The grid is utilized to perform a field of view, image quality, distortion, depth of field and an angle of view tests of the test endoscope. The apparatus further has a fiber optic light guide having one of its ends bifurcated and designed so that the bifurcated ends have the same output for evaluating light transmission through the test endoscope.

A trocar is provided that is adapted to insert a lighting attachment into a body cavity. The trocar connects at its distal end to the lighting attachment such that it can be pushed into the body cavity. An endoscope may then be inserted through the trocar into the body cavity. The lighting attachment is configured to detach from the trocar and attach to the endoscope head to provide additional lighting to the endoscope. The lighting attachment includes foldable lighting panels that expand when in use in order to light a wider field of view. The lighting attachment may be powered by induction coil from the endoscope.

An imaging system includes an imaging scope, a controller, a camera, and a processor. The imaging scope is selectively rotatable about a longitudinal axis relative to a horizon plane. The imaging scope has at least three optical channels, each including a respective objective that captures light. The objectives are positioned such that respective viewing direction axes of the optical channels extend at least substantially parallel to one another. The controller activates a pair of optical channels that is at least as parallel relative to the horizon plane as any other pair of optical channels. The camera generates a first image representative of light captured by a first optical channel of the activated pair of optical channels, and a second image representative of light captured by a second optical channel of the activated pair of optical channels. The processor generates a 3D image using the first and second images.

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 an optical lens system to at least partially even out the information density across an imaging surface area of the imager.
