Optical Spectrum Analyzer (OSA) System

Document Date: 15 April 2026

Background & Scope: The Air Force Research Laboratory, Sensors Directorate, Multispectral

Sensing & Detection Division (AFRL/RYMM) conducts basic and applied research, exploratory development, and advanced technology integration in photonics, optics, and electromagnetic sensing. These efforts directly support United States Air Force (USAF) and Department of War mission objectives by enabling advanced capabilities in electro-optical (EO) sensing and electronic warfare. To maintain technological superiority, these research initiatives rely on the precise characterization, measurement, and analysis of high-fidelity optical signals, components, and systems across a diverse spectral range.

The existing optical spectrum analysis (OSA) inventory within AFRL/RYMM has reached end-of-life (EOL) status and is no longer supported by the Original Equipment Manufacturer (OEM).

The legacy instrumentation exhibits critical operational limitations, including insufficient spectral resolution, inadequate processing speeds, and restricted software and data integration capabilities. These technical deficiencies create significant bottlenecks, hindering the ability of

AFRL engineers and scientists to efficiently execute the testing, characterization, and validation of next-generation optical systems. Acquisition of modernized OSA equipment is required to restore operational readiness and meet current research-and-development parameters.

Requirements/Salient Characteristics: The Optical Spectrum Analyzer (OSA) system must deliver high-resolution, high-speed spectral analysis across a broad wavelength spectrum to support diverse laboratory and experimental applications. Essential capabilities include, but are not limited to, precise optical component characterization, high-fidelity laser source analysis, and comprehensive system-level performance validation.
