rangefinders

[Dragunov]

yeah, those things, not the cameras. (though the Contax II is really sweet)

those 2 meter rangefinders made by Carl Zeiss and the like- do any of you lads know where to find more info on them, in print or on the web (preferably the internet)? all I seem to find is the camera stuff.

cheers!

Hello Dragunov!

Try searching under the German name "Kommandogerät" and see what comes up...

hey, Waleed!

that seems to help, but that's not exactly what I was thinking. so if the 4m+ ones were for arty, what were the 2m ones for? (and what was their German name?)

thanks/cheers/Happy Canada Day

2 Meter ones...?! Do you mean the handheld versions (often seen with arty guys around the 88 gun)?
More like 1 meter - Not quite 2 meter and much shorter than 4 meters

COINCIDENCE OPTICAL RANGE FINDER (Entfernungsmesser 14 nr 500S)

Carl Zeiss, Jena

100*10*10

Metal cylinder of about 10 cm in diameter stands on a tripod. Objective lens with rotating cover at each end and eyepiece at centre. Thumbwheel adjustment at right side. This instrument was used to determine the distance to an object with the use of mirrors and lenses.

The coincidence range finder could be summed up as being made up of two simple telescopes separated by a known distance. With a target object located and a range needed, the range finder is adjusted so that the two fields of view from the two telescopes are given in a single field of view. One is inverted in a central window. This view may be observed through the eye piece located at the centre of the range finder. The two images are brought into coincidence horizontally by adjusting a roller geared to a distance scale.

This technology was primarily developed for the use in artillary in war. With the range to the enemy vital, range finders where easy to use and fairly accurate. They have also been used in such things as range finders for cameras as well as particular surveying jobs.
