Incorporated in 1997 and employee-owned, Lumitek International develops and manufactures photonic products, including phosphor-based infrared and UV visualizers and electroluminescent lamps. Its sensor cards make otherwise invisible radiation visible as a localized glow, while its thin, flexible lamps are made to order for applications such as aircraft instrument-panel and display backlighting. The Ijamsville company also produces matching power supplies and tests every lamp individually for performance and conformance.
