ABSTRACT:
There is disclosed a method of splitting a parallel beam of light indicative of the imaging of an object viewed by a microscope to enable par focal registration of said image at first and second camera locations. A parallel beam of light is directed to propagate through a first input aperture where the beam is converged and then bent at a predetermined distance from the aperture at an angle of 90.degree. to direct said bent beam to the second location where a television camera is positioned to receive the bent beam in proper image orientation and at par focal registration. The converged beam is then diverged as directed through said input aperture and propagated to the first location where a camera is placed for receiving the diverged beam at par focal registration.
