The Seiler 2D Assistant Observer Tube Coupling (#Z-2DBAS) is intended for use with the Evolution xR6, IQ, and Evolution ZOOM ENT Microscopes, as well as Seiler Colposcopes. It allows a second head to be attached to the scope in order for a second person to view the operating surface at the same time as the main user. The tube is attached to a beamsplitter, and a binocular or monocular head is then attached.
