Goetschmann Perspective Control Adapter

The Goetschmann PC (Perspective Control) Adapter is designed to prevent screen image distortion caused by tilting or slanting the projector. It also helps align images when multiple projectors are used. The adapter is installed between the projection lens and projector housing. It allows the lens optical axis to shift horizontally +/- 8mm, vertically +8mm/-7mm, and diagonally +/- 8mm. This adapter works with all Schneider projection lenses except Prolux "C" lenses for perspective control and image alignment in multi-image setups.
