- First dispersive spectroscopy-based benchtop analyzer to support 5-μm band measurement -

1. Yokogawa Test & Measurement Corporation announces that it has developed the AQ6377 optical spectrum analyzer and will release it on January 16. The AQ6377 is a benchtop analyzer that employs the dispersive spectroscopy technique*1 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*2 for instruments of this type.

2. An optical spectrum analyzer is a measuring instrument that resolves the wavelength components of photonics devices such as semiconductor lasers and fiber lasers to evaluate their wavelength characteristics. The AQ6377 will be used to enhance optical devices in the 5-μm band and accelerate their use in environmental measurement and other fields.

3. Since entering the optical spectrum analyzer market in 1980, Yokogawa has continued to develop and refine its technologies for the precision measurement of optical spectra in the visible and near-infrared ranges. Based on its expertise in dispersive spectroscopy, Yokogawa has developed the AQ6377 for mid-infrared measurements, including the 5-μm band.
