    摘要： An adapter (25) for an optical eyepiece (16) for propagating a non-collimated light beam from an object along an optical axis of the eyepiece so as to present an image to an observer (51), the adapter comprising a beam splitter (26) for inserting into the eyepiece so as to intercept the light beam and direct a portion thereof outside the eyepiece through an exit aperture (27) of the beam splitter without substantially changing the image to the observer. The adapter is particularly useful for extracting a portion of an image from an eyepiece having restricted access in a night vision goggles thus permitting an external scene to be recorded simultaneous with its being viewed by the observer.
