LightPath Technologies is lighting the optical networking way. The company, which has traditionally used its patented GRADIUM glass to make distortion-reducing lenses for inspection equipment, is developing new applications for its technologies in the optoelectronics and fiber-optic communications fields. Its optoelectronics products include collimators (optical network components) and optical isolators (filters that prevent light waves from reflecting backwards). LightPath serves such customers as CyOptics, Intel, Santur, ThorLabs, and T-Networks. The company targets aerospace, telecommunications, health care, instrumentation, and the military. LightPath gets about two-thirds of its sales in the US.
