Windows of the first type and windows of the second type are identified within a frame using energy associated with each short window within the frame. A principal planar reflector portion has a principal mirror reflector disposed at the rear substrate and an auxiliary wide angle curved portion has an auxiliary mirror reflector coated at a curved recess established at a region of a second surface of the front substrate or a third surface of the rear substrate by at least one of grinding and ablating. The at least one adjusting device communicates with each of the at least one tapered forcing ring. A focus of the light that is transmitted through the electrooptic material becomes variable by varying an applied voltage between the electrodes of the incident surface and the electrodes of the exit surface.
