摘要
A coincidence and stereoscopic binocular rangefinder is disclosed for measuring distance to sighted targets. The rangefinder preferably has three optical windows for receiving radiation from a sighted target allowing the user to use both his ability to align separated images in one of the eyepieces of the rangefinder, and his ability to stereoscopically sense and compare apparent target depths using both eyepieces of the rangefinder. The rangefinder also includes a novel feature whereby the binocular portion may be easily and conveniently detached from the rangefinder and used separately, and then easily reattached when distance measurement is again desired.
