Applications

The GE Light Valve was General Electric's large-screen CRT-based projection system, developed primarily for professional, military, simulation, and institutional use. Unlike consumer CRT projectors, the Light Valve system used an oil-film light modulator — a technology GE pioneered — to achieve very high brightness and large-screen image quality for its era. These systems were used in flight simulators, command-and-control centers, training facilities, and large-venue presentation environments from the 1960s through the 1980s. The FI-130 lens with its 4.9:1 throw ratio was a standard optical component for these installations. Today, GE Light Valve components are sought by simulation historians, restoration enthusiasts, and institutions maintaining legacy projection systems.
