Nanoptics, Inc., offers custom, made-to-order plastic optical fiber (POF) - an original equipment manufacturer (OEM) for advanced specialty applications requiring low-weight, flexible plastic fiber optics. Building on work during the late sixties in the field of scintillating plastic optical fiber, the company is the largest U.S. manufacturer of fluorescent plastic optical fiber for use in aiming devices for archery and other weapons systems.The company holds patents on a special fluorescent fiber which permits the sight to operate in total darkness as well as bright ambient light. Nanoptics' other custom fibers are used in specially made optical products, including but not limited to optical sensors, digital communications and imaging elements (faceplates, endoscopes, and boroscopes). Nanoptics has developed POF light guides with the largest numerical aperture in the industry that are used in situations where maximum transmitted light intensity is critically important, as in medical applications. The company also fabricates scintillating, wavelength shifting and fused fiber optic bundles and devices on a custom basis. Research efforts have resulted in the production of coherent bundles of thousands of plastic optical fibers used in fiberscope image guides for medical and industrial applications. Nanoptics introduced the Nanoscope⢠which was the first plastic fiber optic endoscope in medical history
