Yokogawa AQ6150B 900-1700nm Optical Wavelength Meter

The Yokogawa AQ6150B is a precision optical wavelength meter designed for accurate characterization of light sources and components across the 900 nm to 1700 nm spectrum. Built for telecommunications, component manufacturing, and research environments, it delivers wavelength measurements with ±0.01 nm accuracy and 0.001 nm resolution in under half a second per point. The instrument accepts optical signals from -70 dBm to +20 dBm, making it suitable for both weak and moderate-power sources. Its color LCD touchscreen provides intuitive operation, while USB, LAN, and optional GPIB connectivity enable integration into automated test systems and remote monitoring workflows. Wavelength stability of ±0.005 nm/hour ensures repeatable results across extended measurement sessions.
