New! 818-xx-L-FC/DB Photodiode Fiber Optic Detectors are a low cost alternative to the 818-IS or 918D-IS Series. The detectors are based on the industry standard 818 Series detectors with a new 884-FC fiber optic adapter mounted on it. UV Silicon, Silicon, Germanium, and InGaAs versions are introduced. FC/APC and SMA connectors can easily accommodated by replacing the 884-FC with 884-FCA and 884-SMA, respectively. Unscrewing the fiber adapter makes it a free space detector as well.
Model 918D-IS-1 Universal Fiber Optic Sensors use a 1" symmetrical integrating sphere to ensure the most accurate calibration possible, regardless of the fiber type measured. The integrating sphere uses a dual detector design, with special optics that improve temperature sensitivity markedly from ordinary detectors, with the wavelength range of 400–1650 nm. The 918D-IS-IG uses a single InGaAS detector (800-1650 nm) while the 918D-IS-SL uses a single Si detector (400-1100nm). The calibration data is encoded in a calibration module integral to the electrical connector.
An FC, ST, LC, and SC fiber adapters included, 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, which is also included. The complete kit is packaged in a rugged carrying case.
To maintain accuracy and guarantee performance Newport recommends annual recalibration. Newport offers many Optical Sensor Calibration Services including the new ANSI Z450.3 compliant calibration.
Note about 818-IS-1 and 818-xx-L Series Detectors
Please note that the model 818-IS-1 and the free-space 818-xx-L Series Photodiode Detectors are available for purchase offline only. Contact Sales@newport.com for a sales inquiry.
Which Connector Type to Choose?
An example of the DB15 (left) and the 8-pin DIN (right) style calibration module, respectively.
The 918D-IS series models come with the DB15 calibration module permanently attached to the cable. The 818-xx-L-FC/DB models with /DB suffix come with a detachable BNC/DB15 calibration module that provides direct compatibility with Newport's active power meters. The 818-IS-1 model comes with a round 8-pin mini-DIN calibration module that provides compatibility with legacy Newport power meters. In both cases, the adapters contain the detector calibration data, model number, serial number and calibration date for seamless operation with the power meter.
