ABSTRACT:
An optical adapter is provided by which an image formed by the eyepiece of an optical viewing device such as an endoscope can be simultaneously viewed and photographed with a motion picture camera of the type having a through-the-lens viewing system which has an entrance pupil that occupies only a portion of the entrance pupil of the camera's optical taking system and which is positioned off the optical axis of the camera's optical taking system. The adapter operates to spread the optical viewing device's exit pupil so that its size matches that of the camera's entrance pupil and to improve the uniformity of illumination of the camera's viewing system and taking system.
