Optics For Research, Inc. [ Optics For Research ]
OFR was established in 1976 to manufacture and market precision optical components and instruments for use in university, government and medical research, the military, research and development, and other industrial applications.
In 1985, OFR developed the first optical isolator in the United States. OFR then entered into a new market and today manufactures more isolator models than any other producer in the world. Isolators led OFR into the fiber optics market, and, today, OFR is a major supplier of specialized fiber-optic devices and components for the R&D and OEM markets.
Since its inception, OFR has earned a reputation as a reliable manufacturer of superior quality, precision optical components, isolators, and fiber-optic "building-block" components.
Meet OFR technical sales and engineers at major shows and conferences, such as Photonics West, OFC, CLEO , and at numerous international shows.
