Abstract
An optical viewing system includes an optical viewing device in a housing having a socket at its inner end for application to a person's finger, a focussing lens at its outer end for focussing images in the region in front of the focussing lens, and an image sensor for transforming the images to electrical signals. A remote monitor unit receives the electrical signals and displays the images received by the image sensor.
