The Yokogawa AQ6370C optical spectrum analyzer is a versatile instrument for analyzing the spectral characteristics of light sources and optical components. With a wavelength range of 600 to 1700nm, it can be used to measure the spectral width, center wavelength, and side mode suppression ratio of lasers, as well as the insertion loss and return loss of optical filters and other passive components. The AQ6370C’s high wavelength accuracy and resolution ensure precise measurements, while its wide dynamic range allows for the analysis of both strong and weak optical signals.
