The Yokogawa AQ6370C is a high-performance optical spectrum analyzer (OSA) designed for the 600 to 1700 nm wavelength range. Well-suited for both research and development and manufacturing environments, it is available in standard (AQ6370C-10) and high-performance (AQ6370C-20) editions. Featuring an advanced monochromator with a stray-light suppression ratio that enables a dynamic range of up to 78 dB, the AQ6370C supports both single-mode and multimode optical fibers through a unique free-space optical input.
