DESCRIPTION:

The Yokogawa AQ6373B is a high-performance optical spectrum analyzer specifically designed for accurate measurement and analysis of visible and short-wavelength optical signals from 350 nm to 1200 nm. As part of the renowned AQ6370 Series, the instrument delivers the speed, sensitivity, and resolution required for advanced optical research, development, manufacturing, and quality assurance applications.

The AQ6373B is ideally suited for characterization of laser diodes, fiber lasers, LEDs, optical filters, fiber Bragg gratings, photonic components, biomedical devices, and optical communication systems operating within the visible and near-infrared wavelength regions. Its wide measurement range allows engineers and researchers to evaluate a broad range of optical devices using a single platform.

Featuring wavelength resolution down to 0.01 nm in the visible region and wavelength accuracy of ±0.05 nm, the analyzer provides highly detailed spectral measurements for demanding photonics applications. The instrument also incorporates colour analysis functions, built-in optical alignment capability, and support for single-mode, multimode, and large-core optical fibers.

The free-space optical input design improves measurement flexibility while reducing connector wear and maintenance requirements. Fast sweep technology and high-speed remote interfaces enable efficient automated testing and production-line integration.
