Yokogawa AQ6374
The AQ6374 Wide Range Optical Spectrum Analyzer covers wavelengths from 350 to 1750 nm including visible lights (380 to 780 nm) and the telecommunication wavelengths.
The AQ6374 optical spectrum analyzer is capable of covering both the visible light wavelengths and the wavelengths used in optical communications. With a maximum resolution of 2 pm and the ability to sample power levels at up to 100,000 wavelength points, the AQ6374 can precisely evaluate and analyze a wide range of wavelengths with a single scan. The AQ6374 also features a wide close-in dynamic range of 60 dB, which is sufficient for measuring the side mode characteristics of a semiconductor laser
