Abstract
An optical combiner for use with an optical eyepiece which is adjusted for viewing a first image, and which injects a non-collimated light beam from a second image substantially along an optical axis of the eyepiece so as to present a combined image to an observer. The combiner comprises a beam splitter for inserting into the eyepiece and having an entry aperture for intercepting the non-collimated light beam and directing a portion thereof outside the eyepiece so as to superimpose the second image on the first image.
