Abstract
A documentation illumination module by which full illumination of a properly oriented image of a microscope's field-of-view is returned to a documenting camera or the like. The module includes a cavity with a forming and field-of-view-controlling lens system, channel for returning the image, focusing and magnifying lenses in the image channel, and an iris across the image channel. Fiber optics light is transmitted through the cavity and its lens system to a microscope and its field-of-view, then returned to module and to binoculars for an observer (surgeon), without need of beam splitting optical elements. Full light is available to camera and observer. The focusing and magnifying lenses are mounted in an alternatively positionable lens system, while a zoom lens assembly can be substituted therefor.
