The Ohio State University Image-Dissector Scanner (IDS) is now routinely operational on the Perkins 1.8-m reflector of Ohio Wesleyan University and The Ohio State University at the Lowell Observatory. The electro-optical design of the detector is similar to that of the image-tube scanner constructed by Robinson and Wampler at the Lick Observatory. The detector is mounted in a Cassegrain spectrograph with 10-cm-diameter optics. Operation of both the detector and the spectrograph are controlled by a PDP-11/20 minicomputer through a CAMAC interface. Performance of the IDS is adequate for the observational programs currently underway and the overall sensitivity of the system is competitive with similar instruments in use on other telescopes. Auxiliary television acquisition and guiding systems, data reduction, and plans for future development are also discussed.
