LPTH

Lightpath Technologies Inc

A maker of precision optical and infrared lenses and cameras, LightPath Technologies supplies thermal-imaging systems used in defense, border security, and counter-drone work. Founded in 1985 and based in Orlando, Florida, it grew from a component supplier into a vertically integrated optics house through acquisitions like G5 Infrared. Its signature material is BlackDiamond, a chalcogenide glass made in the U.S. that substitutes for germanium, the usual infrared optic material that China dominates.
