Newport has introduced a series of photodiode-based fibre optic detectors. The new products are alternatives to existing 918D-IS integrating sphere fibre detectors, that allow both free-space and fibre optic measurements simply by removing the fibre adapter.
Based on Newport’s 818 detector series, the new fibre optic detectors feature great flexibility and simple configuration with three stainless steel adapters available. The FC/PC adapter is included; the optional FC/APC and SMA connectors are both sold separately. Four different detectors are introduced: ultraviolet (200 – 1100nm); silicon (400 – 1100nm), indium gallium arsenide (800 – 1650nm), and germanium (780 – 1800nm).
The 918D-IS series universal fibre optic sensors use a one-inch symmetrical integrating sphere to ensure accurate calibration, regardless of the fibre type measured.
The dual detector design includes special optics to improve temperature sensitivity, operating wavelength from 400 to 1650nm. The 918D-IS-IG has a single InGaAs detector that operates from 800 to 1650nm while the 918-IS-SL uses a single Si detector for operation in the wavelength range from 400 to 1100nm.
