Abstract
An optical coupler or photo adapter unit has an input port located on a first surface of a housing for receiving a parallel beam of light as may be derived from a microscope or beam splitter. The input port is associated with a first lens for converging the parallel beam. A first output port is located on a surface of the housing transverse to said first surface; and a second output, relatively coaxial with said first port, is located on a surface relatively parallel to the first surface. A second lens is located adjacent the second output port and is operative to diverge the light as transmitted through the second output port as received from said first port and lens. Positioned within the housing and located between the input port and second output port is a selectively pivotable mirror, which when selected in a first position, causes light from said input port to be reflected to said first output port and to block light from the second output port; and in a second position, said mirror operates to block light at said first output port to thence direct light to said second output port. The mirror and lenses operate to assure that suitable photographic apparatus coupled to said ou…
