3 - DUKANE MODELS 663, 4003, 4500 & 5500
Professional Overhead Projectors
The Models 663, 4003, 4300 and 5500 feature a special optical design
which combines a standard three-element (13") projection lens with a
movable fourth element that converts to a wide angle (11”) lens.
This design allows you to maintain image size for both transparency
and the smaller LCD panel aperture size. Other features include a
lamp changing mechanism and spare lamp indicator that will light
up to remind you to replace the primary lamp.
