Abstract
A reflex sight comprises two apertures. One aperture is a direct view optical path of the target scene. The other aperture is a digital (e.g., thermal) camera or image intensifier. A beam combiner with two reflective surfaces (for example, a Bauernfeind, Penta, or other prism bonded to a wedge prism) and afocal eyepiece optics overlay the digital image or intensified image onto the direct view scene with matched magnification.
