ABSTRACT:
Information relevant to a remote instrument is made viewable within a microscope 10 by a heads up display using a beam splitter 15 arranged in a collimated light region between binoculars 12 and objective 11 of microscope 10. An electronic digital display 16 relevant to a control setting for the remote instrument is arranged off the optical axis of microscope 10 and viewed by a convex mirror 20. A folding mirror 21 directs diverging light from convex mirror 20 toward beam splitter 15, and a collimating lens 22 collimates the diverging light enroute from folding mirror 21 to beam splitter 15. Collimated light from the lens is incident on beam splitter 15 to position an image of the digital display in a marginal region of the apparent field of one of the binoculars 12.
