This unit
The Yokogawa AQ6376E is a bench-top optical spectrum analyzer covering 1500–3400 nm, extending into the Mid-Wave Infrared region. It delivers high-accuracy wavelength measurements, exceptional sensitivity down to −65 dBm, and a 78 dB measurement dynamic range. The instrument supports both free-space and fiber-coupled inputs (single-mode and multimode up to 400 µm) and executes full-span sweeps in as little as 0.5 seconds using Double Speed Mode.
Built-in gas purging, cut filtering, and fast auto-calibration eliminate common measurement artifacts. Advanced Pulsed Light Measurement capability and a double-pass monochromator design enable precise characterization of environmental gases (COx, NOx, CxHy), laser sources, and infrared optical components in R&D and manufacturing environments.
