A four-page data sheet from Fiberguide Industries Inc. describes the company’s Superguide PCS silica fiber, which has a numerical aperture of 0.37 and plastic cladding that allows a high core-to-clad ratio. It notes that the fiber is particularly suitable for UV transmission and that it provides more efficient light coupling. The sheet lists fiber features, including reduced static fatigue in humid environments, as well as applications in the industrial, scientific and medical fields. It presents a cross section, a spectral attenuation graph and specifications, including core and clad diameters, temperature operating range, minimum bend radius and typical standard length for the various types offered.
