Model 818-IS-1 and 918D-IS-1 Universal Fiber Optic Sensors use a symmetrical integrating sphere design to ensure the most accurate calibration possible, regardless of the fiber type measured. The integrating sphere uses a novel dual detector design, with special optics that improve temperature sensitivity markedly from ordinary detectors. Both are fully calibrated to a traceable standards over the wavelength range of 400–1650 nm. The 918D-IS-IG uses a single InGaAS detector and is calibrated over the range of 800-1650 nm. The 918D-IS-SL uses a single Silicon detector and is calibrated over the range 400-1100nm. The calibration data is encoded in a calibration module integral to the electrical connector. The 818-IS-1 is compatible with Newport's legacy power meters utilizing calibration modules, while the 918D-IS versions have an integral DB15 connector and are compatible with Newport's new power meters.
Maximum versatility is provided by the detector’s dual port design. A variety of adapters for connector-terminated fibers are provided, and plug into the detector’s front port. The rear port is designed to measure light from straight and angle cleaved bare fibers, using Newport’s FP3-FH1 bare fiber holder. A complete kit of adapters is included with each detector, together with a rugged carrying case.
818-IS-1 shown. 918D-IS Series are terminated with a 15-pin D-Sub connector.
A bare fiber holder and various fiber optic connector adaptors are provided with all Universal Fiber Optic Detectors (LC adapter not shown).
