摘要

A viewing instrument having a variable direction of view is disclosed generally comprising a shaft, a sensor mounted in the distal end of the shaft such that the image plane of the sensor is substantially parallel to the longitudinal axis of the shaft, and a reflecting element that rotates about an axis substantially perpendicular to the longitudinal axis of the shaft. In some embodiments, a negative lens is mounted adjacent the reflecting element, and in certain embodiments, a positive lens is positioned adjacent the image sensor.
