Kopin Corp
A maker of tiny high-resolution micro-screens and optical systems that sit inside head-mounted goggles and visors — including the F-35 fighter jet pilot's helmet — for military, medical, industrial, and consumer use. The company was founded in 1984 by materials scientist Dr. John C.C. Fan as a spin-off from MIT's Lincoln Laboratory, where he had researched nano-engineered materials. Though its name rarely appears on retail shelves, Kopin's displays power helmets and visors built by aerospace and defense partners.
