Image deflector for gun sights

摘要

Optical apparatus in which a beam deflector is used to reposition the sight beam from a reflex sight. In one example, an optical apparatus includes a reflex sight configured to produce a collimated reflex sight beam directed along an optical axis, and a beam deflector coupled to an output of the reflex sight and configured to deflect the reflex sight beam by a selected angle of deflection relative to the optical axis to reposition an eyebox of the reflex sight off-axis with respect to the optical axis and remote from the reflex sight. In certain examples, the optical apparatus also includes a telescopic sight, and the beam deflector is configured to deflect the collimated reflex sight beam to overlap the reflex sight beam with the exit pupil of the telescopic sight.

主权项

1. An optical sighting apparatus comprising:
a telescopic sight configured to produce an exit pupil; a reflex sight configured to produce a collimated reflex sight beam; and a beam deflector coupled to an output of the reflex sight, the beam deflector being switchable between an ON position and an OFF position, and including a pair of prisms, each prism of the lair of prisms including a first prism element and a second prism element, in the ON position, the beam deflector being configured to deflect the collimated reflex sight beam to produce a deviated reflex sight beam and to overlap the deviated reflex sight beam with the exit pupil of the telescopic sight, and wherein when the beam deflector is in the OFF position, the collimated reflex sight beam is non-deviated.
