Endoscopes. Medical endoscopes and endotherapy devices - Determination of field of view and direction of view of endoscopes with optics1 Scope This document applies to endoscopes designed for use in the practice of medicine. It specifies measurement requirements and describes two test methods for measuring the field of view and direction of view of endoscopes. Method A uses the distance from the distal window to calculate the field of view. Method B uses the distance from the entrance pupil.
