Coincidence rangefinders work through the principle of triangulation. In the pictured example, triangulation can be used to determine the range of the ship ๐.The position of the lenses A and B are known, and the angle of the lenses α and/or β is set by the operator so that both are aimed at the target.
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...

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 ...
Rangefinders first hit the hunting market over two decades ago. Back then we were excited by new tech on the horizon but it didn't quite cut the mustard. It didn't do what we expected it to do ...
The only true zoom lens for rangefinder cameras is the Contax G2 Carl Zeiss 35–70 mm Vario-Sonnar T* Lens with built-in zoom viewfinder. [7] A very few lenses, such as the Konica M-Hexanon Dual or Leica Tri-Elmar, let the user select among two or three focal lengths; the viewfinder must be designed to work with all focal lengths of any lens used.
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.
Early in World War II, the range to the target was measured by optical rangefinders. Though some night operations were conducted using searchlights and star shells, in general optical rangefinders were limited to daytime operation. [10] During the latter part of World War II, radar was used to determine the range to the target.
