IMAX® - More Information

The Experience

IMAX® motion picture systems, invented and developed by IMAX Corporation (IMAX), are the finest motion picture systems in the world. Images of unsurpassed size, clarity and impact, enhanced by a superb specially designed six-channel, multi-speaker sound system, are projected onto giant rectangular screens up toe ight stories high, in the case of IMAX, and, in the case of IMAX DOME® (OMNIMAX®), onto domes as large as 88 feet-five inches (27 meters) in diameter.

The Film

The IMAX image is ten times larger than a conventional 35 mm frame. The sheer size of an IMAX file frame, combined with the unique IMAX projection technology, is the key to the extraordinary sharpness and clarity of IMAX films.

The Projectors

IMAX projectors are the most advanced, highest-precision and most powerful projectors ever built. The key to their superior performance and reliability is the unique "Rolling Loop" film movement. The Rolling Loop, originally invented by Ron Jones, an Australian, adapted and enhanced by IMAX, advances the film horizontally in a smooth, wave-like motion. During projection, each frame is positioned on fixed registration pins, and the film is held firmly against the rear element of the lens by a vacuum. As a result, the picture and focus steadiness are far above normal standards.
