Specifications

Features

High Performance Universal Detectors

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.

Tightest Calibration Uncertainty

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.

Integrating sphere with novel dual detector design

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.

Variety of Fiber Adapters Included

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.

Portable Versatility

Each 918D-IS Series detector and its accompanying connector and bare fiber adapters come in a rugged carrying case that protects the equipment during transportation or storage, making it easy to carry the system from one lab to another.
