The 918D-IS-IG Fiber Optic Detector uses a symmetrical integrating sphere design to ensure the most accurate calibration possible, regardless of the fiber type measured. The 918D-IS-IG uses a single InGaAs detector and is calibrated over the range of 800-1650 nm. The calibration data is encoded in a calibration module integral to the electrical connector. The 918D-IS-IG has an integral DB15 connector and is compatible with Newport's new power meters. Maximum versatility is provided by the detector’s dual port design. A variety of adaptors 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 adaptors, including the FP3-FH1, is included with each detector, together with a rugged carrying case.
