must be merged Edit
This page absolutely needs to be merged with Rangefinder. The first sentence is utter nonsense: "A coupled rangefinder is a focusing device for rangefinder cameras." --Rebollo fr 19:18, 28 August 2006 (EDT)
- Done. --Rebollo fr 18:08, 9 October 2006 (EDT)
The explanation is a little wrong here; the image you see is not split by the beamsplitter, it's two separate images that are combined. (of course, a principle of optics is that all rays are reversible...) The bit at the end about parallax is also not quite right; this is referring to the viewfinder, not the rangefinder (you could attach a rangefinder to an SLR and have no viewing parallax); rangefinders may suffer from parallax if not placed properly or parallel to the focal plane - perhaps this ought to be removed.
I'll think about better words; I started but made it worse, so cancelled that part of the edit.

The article certainly looks better now. Some minor points are neglected though:
- not all rangefinders are combined with the viewfinder, older models have a separate rangefinder (and three windows at the front), including well-known cameras such as the Leica screw models
- not all rangefinders use a beam splitter, some use a split image instead, either with a separate second image moving inside the viewfinder, as in the Leningrad or Werra, or with a separate eyepiece showing two images separated by a horizontal line, as on the Super Baldina
