[Original] IdealPhotonics shared the introduction-Yokogawa AQ6377 spectrometer

2024-11-16 15:14:18

Yokogawa AQ6377 spectrometer is based on the diffraction principle, which is different from the usual interference spectrometer. It is mainly used for mid-infrared lasers and effectively solves the problem of measuring waveforms by mid-infrared lasers. It uses dispersion spectroscopy technology to measure the laser spectrum in the wavelength range of 1.9um-5.5um, which has the characteristics of high precision, wide dynamic range and high resolution. Dispersion spectroscopy technology is a kind of technology that allows light to pass through a diffraction grating to disperse and pass through a narrow slit, so as to extract light in a specific wavelength range.
