Abstract
Abstract The device and method relates to a range finder which can be used in conjunction with guns, cameras and similar articles, the device employing a source of radiant energy to produce a spot on the target, the spot being discernible on a reticule, the line of sight and the beam of radiant energy being related to that the apparent position of the spot on the reticule can be used to indicate the range.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
In a range finder for determining the range to a target by the eye, the combination including a single reticule having indicia, a radiant energy spot producing source for providing a spot of energy on the target, means supporting said reticule and said energy source in fixed spatial relationship and in angular relation to each other, means for positioning the eye relative to said reticule and said energy source, a line from the eye of the user to the projected spot of energy on the target and the axis of the beam of the energy source being in the same plane, so that different ranges can be continuously determined by the eye directly from the apparent position of said spot relative to indicia on said reticule, said spot being actually superimposed on the target.
Claim 2
Dependent Claim
134 words

Claim 3
Dependent Claim
32 words
A device according to claim 1 wherein the reticule has calibrated indicia between indicia indicating the range and vertical sighting indicia means so as to provide compensation for trajectory of a projectile.
Claim 4
Dependent Claim
30 words
A device according to claim 3 wherein there is an objective lens, an inverting lens, an eye piece, and a reticule, the reticule being between the eyepiece and inverter lens.
Claim 5
Dependent Claim
14 words
A device according to claim 1 wherein the radiant energy source is a laser.
