Newport Corp. offers its photodiode-based fiber optic detectors, intended as an alternative to existing 918D-IS integrating sphere fiber detectors and allowing both free-space and fiber optic measurements by removing the fiber adapter.
Based on Newport’s 818 detector series, the fiber optic detectors can be configured with three stainless steel adapters – the FC/PC adapter is included; the , and the optional FC/APC and SMA connectors are both sold separately.
Four different detectors are introduced: Ultraviolet (UV – 200 – 1100 nm), silicon (Si – 400 – 1100 nm), indium gallium arsenide (InGaAs – 800 – 1650 nm), and germanium (Ge – 780 – 1800 nm).
The 918D-IS series universal fiber optic sensors use a 1-in. symmetrical integrating sphere to ensure the most accurate calibration possible, regardless of the fiber type measured. The dual detector design includes optics to improve temperature sensitivity, operating wavelength from 400 to 1650 nm. The 918D-IS-IG has a single InGaAs detector that operates from 800 to 1650 nm, while the 918-IS-SL uses a single Si detector for operation in the wavelength range from 400 to 1100 nm.
