Abstract
A tool is disclosed for evaluating the alignment of the channel of an endoscope. The tool includes a housing with one end thereof being connectable to the endoscope. The other end of the housing includes an eyepiece. A lens system is provided within the housing for imaging the distal end of the endoscope onto a reticle. The position of the image on the reticle allows the axial alignment of the endoscope channel to be evaluated.
