| 摘要 |
A dual optical path adapter is provided by which a camera of the type having a through-the-lens viewing system can be mechanically and optically coupled with the eyepiece of an optical viewing device such as an endoscope so that a viewable image which is formed by the endoscope can be simultaneously viewed along a first optical path of the adapter and photographed and/or viewed, via the camera, along the adapter's other optical path. The adapter is structured so that the camera can be moved between a number of positions without introducing any reversals of the object image as directly observed through the adapter's first optical path. In this manner, the camera can be focused while in one position and thereafter moved for photographing to any of its other positions which are more comfortable for the photographer.
