Applications
Overhead projectors of this type were a standard presentation and teaching tool from the 1950s through the 1990s, widely used in classrooms, corporate training rooms, and lecture halls to project transparency films (acetate sheets) onto a wall or screen. The Transpaque Auto Level design was aimed at professional and institutional users who needed a stable, well-aligned image without manual keystone correction. Projection Optics Co. Inc. was a U.S. manufacturer based in New Jersey that produced projectors for the education and business markets during this era. Today, units like this are sought by collectors of vintage audio-visual equipment, schools or organizations that still use overhead projector transparencies, and repair technicians looking for parts.
This Projection Optics Model 20400 Transpaque Auto Level Overhead Projector powers on and the cooling fan runs, but the lamp does not illuminate — the 1000W bulb appears to be burned out. It is being sold AS-IS for parts or repair, with no warranty. No manual or accessories are included. The unit shows age-appropriate wear consistent with previous use; the housing has some scuffs and discoloration typical of older equipment. An Exxon asset label is affixed to the front of the housing. Please view our photo set and contact us if you have any questions.
