YOKOGAWA AQ6377 Optical Spectrum Analyzer 1900 – 5500 nm

The AQ6377 is a benchtop analyzer that employs the dispersive spectroscopy technique to measure the optical spectra of laser light in the 1.9–5.5 μm wavelength range with high accuracy, wide dynamic range, and high resolution.

The support of measurements in the 5-μm band is an industry first for instruments of this type.

Key features of the AQ6377 include gas purging input ports/output ports, a built-in cut filter for high order diffracted light​​​​​​, and a novel double speed mode which increases the sweep speed up to 2 times compared to the standard sweep mode.
