DESCRIPTION:

The Yokogawa AQ6376 Optical Spectrum Analyzer is a high-performance long-wavelength optical measurement platform designed for engineers, researchers, and photonics specialists working with optical signals in the 1500 nm to 3400 nm wavelength region. The instrument extends optical spectrum analysis capabilities beyond conventional telecommunications wavelengths, supporting advanced research and development applications across infrared photonics, sensing, and laser technologies.

The AQ6376 is particularly suited for characterization of fiber lasers, tunable lasers, optical amplifiers, environmental sensing systems, gas analysis applications, medical photonics, and next-generation optical communication technologies operating in the short-wave infrared region. Its extended wavelength coverage enables detailed analysis of optical devices that cannot be measured using traditional telecommunications-focused optical spectrum analyzers.

Featuring a free-space optical input design, the AQ6376 accommodates both single-mode and multimode fiber measurements while minimizing connector wear and improving measurement flexibility. The analyzer provides high sensitivity, excellent wavelength accuracy, and high dynamic range, allowing detailed spectral analysis of complex optical signals and laser sources.

The instrument incorporates advanced measurement and analysis functions including peak search, spectral width analysis, side-mode suppression ratio measurements, filter analysis, and automated testing capabilities. Fast sweep performance and remote control interfaces support both laboratory research and automated production test environments.
