ABSTRACT:
A binocular endoscope which uses a pair of coherent fiberoptic channels and associated objective lens systems which incorporate a "zoom" feature of magnification while preserving depth perception for the user. There are two longitudinally spaced lenses in each objective lens system. The endoscope is inserted into a body cavity and the object to be examined is brought into focus with the lenses separated at or near their minimum spacing in order to establish orientation within the body cavity. After orientation is established, the spacing between lenses is reset to be at or near its maximum distance between lenses and the scope is advanced axially to its fixed focal plane. Thereafter, the field of view and its concomitant magnification are varied without changing the axial position of the scope with respect to the patient.
