The IMAX® projector is the most advanced, highest-precision, most powerful projector ever built.
The key to its superior performance and reliability is the unique "Rolling Loop" film movement.
The Rolling Loop advances the film horizontally through the projector in a smooth, wave-like motion; during projection, each frame is positioned on fixed registration pins, and the film is held firmly against the reer element of the lens by vacuum.
As a result, the picture and focus steadiness are far above normal standards and print life is substantially increased. The patented projector shutter mechanism in an IMAX® projector transmits one-third more light than the shutter in conventional projectors. The advanced wide-angle lenses are designed especially for Imax Corporation by Hughes Leitz Optical Technologies Ltd.
