American soldiers using a coincidence rangefinder with its distinctive single eyepiece during army maneuvers in the 1940s. A coincidence rangefinder or coincidence telemeter is a type of rangefinder that uses the principle of triangulation and an optical device to allow an operator to determine the distance to a visible object.
Rangefinders may be used by users of firearms over long distances, to measure the distance to a target to allow for projectile drop. [10] Until the development of electronic means of measuring range during the Second World War, warships used very large optical rangefinders—with a baseline of many meters—to measure range for naval gunnery.
A stereoscopic rangefinder or stereoscopic telemeter [1] is an optical device that measures distance from the observer to a target, using the observer's capability of binocular vision. It looks similar to a coincidence rangefinder, which uses different principles and has only one eyepiece. German instruments tended to use the stereoscopic ...

Rangefinder Camera Mechanism. Some cameras do not have a beam splitter; these cameras instead have a separate viewfinder.The first rangefinders, sometimes called "telemeters", appeared in the twentieth century; the first rangefinder camera to be marketed was the 3A Kodak Autographic Special of 1916; the rangefinder was coupled.
Unless you're really fond of its lens system, Leica's M-series range-finders have always been a tough sell -- models like the M8 and M9 have limited features, and they cost a fortune. Leica has ...
To do this, it had optical sights (the rectangular windows or hatches on the front), an optical rangefinder (the tubes or ears sticking out each side), and later models, fire control radar antennas. The rectangular antenna is for the Mark 12 FC radar, and the parabolic antenna on the left ("orange peel") is for the Mark 22 FC radar.
A stadimeter is an optical device for estimating the range to an object of known height by measuring the angle between the top and bottom of the object as observed at the device. It is similar to a sextant , in that the device is using mirrors to measure an angle between two objects but differs in that one dials in the height of the object.
