Fiber Optic Detectors
IRVINE, Calif., Jan. 28, 2013 — Newport Corp. has introduced photodiode-based fiber optic detectors, alternatives to existing 918D-IS integrating sphere fiber detectors. They enable free-space and fiber optic measurements by removing the fiber adapter.
Based on the company’s 818 detector series, they feature simple configuration, with three stainless steel adapters available. The FC/PC adapter is included, and the optional FC/APC and SMA connectors are both sold separately. Four detectors are available: ultraviolet (200 to 1100 nm), silicon (400 to 1100 nm), InGaAs (800 to 1650 nm) and germanium (780 to 1800 nm).
The 918D-IS series universal fiber optic sensors use a 1-in. symmetrical integrating sphere to ensure accurate calibration, regardless of the fiber type measured. The dual-detector design includes special optics to improve temperature sensitivity over an 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 silicon detector for operation from 400 to 1100 nm.
Newport’s calibration service to help maintain accuracy and guarantee performance includes the new ANSI Z450.3-compliant calibration.
