The 918D-IS-1Universal Fiber Optic Detector uses 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. It is fully calibrated to traceable standards over the wavelength range of 410–1650 nm. The calibration data is encoded in a calibration module integral to the electrical connector. The 918D-IS-1 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.
The 918D-IS Series symmetrical integrating sphere is constructed from a highly reflective thermoplastic, resulting in much better measurement stability under varying conditions of temperature, humidity and long-term usage compared to conventional coated spheres. The 918D-IS-1 features a dual detector and is fully calibrated over the very broad wavelength range of 400-1650 nm. The 918D-IS-IG has a single InGaAs detector and is calibrated from 800-1650 nm, and the 918D-IS-SL has a single silicon detector and is calibrated from 400-1100 nm. Included with each detector are adapters for bare fiber and FC, ST, LC, SC and SMA connectors, making the 918D-IS a universal fiber optic detector. 918-IS Series detectors have a DB15 connector integrated into the end of their cable and are compatible with all of Newport's optical meters that accept such a connection.
Newport's detectors include a full spectral response calibration utilizing NIST-traceable standards calibrated with high-precision equipment maintained in Newport’s optical detector calibration facility. Tight calibration facility and process control allows the tightest calibration uncertainty in industry. Each detector is shipped with the calibration data, which is electronically stored inside the detector's EEPROM. A certificate of calibration as well as the actual calibration curves and data with and without the attenuator are shipped with each product. To maintain accuracy and guarantee performance Newport recommends annual photodiode detector calibration.
A variety of fiber adapters are included with every Sphere-Based Fiber Optic Sensor. A Blank Plug (22497-01) , bare fiber adapter (FP3-FH1), FC (22494-01), ST (22493-01), LC (31850-01S) and SC (31856-01S) adapters are included. An SMA (918D-IS-SMA) Fiber Adapter for the 818-IS and 918-IS is also available for purchase separately. The 884-ADAPT will allow the fiber adapters for the 918D-IS series detectors to be mounted on the 818 and the 918D series free space detectors.
The 918D-IS-1 Universal Fiber Optic Detector uses a symmetrical integrating sphere design for the maximum calibration accuracy regardless of the fiber type being measured. Its integrating sphere incorporates a novel dual detector design with special optics that dramatically improve temperature sensitivity compared with ordinary detectors. It is fully calibrated to traceable standards over the 410-1650 nm wavelength range. Other features include calibration data encoded in a calibration module integral to the electrical connector, an integral DB15 connector, compatibility with Newport’s new power meters and a versatile dual port design. A complete kit of adapters, including the FP3-FH1, is included with each detector, along with a rugged carrying case.
