ABSTRACT:
A portable endoscope tester determines specific properties of an endoscope optical system and enables comparisons between individual endoscopes to be made. The tester includes a holder for receiving and aligning an endoscope and a target attachable to the holder. The target is held in a plane normal to the optical axis of the endoscope when received in the holder. Opaque indicia indicative of the optical properties of the endoscope appears on the target and include a central disk with either a pinhole or a cross formed at the center, a plurality of field circles including an inner and outer bold ring, an inner and outer group of resolution targets arranged at respective clock positions, each resolution target comprising a plurality of parallel lines of different width and spacing, and rectangular grid centered on the optical axis. Depth of field, magnification, clarity, resolution, tilted de-centered optical color fringing, field and direction of view, coma and fall-off of resolution from the center to the edge can be detected.
