Abstract
Procedures of mating the needle-shaped unit of a rigid endoscope, which includes GRIN objective and translator, and a color video camera are presented. It is shown that a uniform flat-convex lens introduced to the system easily eliminates the chromatic aberration of position and magnification, and an additional uniform meniscus lens minimizes the aberrations of thin beams.
