One of the byproducts of the prism binocular is a special long range folding stereo telescope (Scherenfernrohr in German) for observation and range-finding in a military environment. The author describes one such instrument that was handed down from his grandfather from World War I. There are other instruments as well such as the coincidence rangefinder that were developed from this research.
