Abstract
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.
