Agilent AGILENT 86120C Optical Multi-Wavelength Meter

The Agilent 86120C Multi-Wavelength Meter measures the wavelength and optical power of laser light in the 1270 to 1650 wavelength range. Because the Agilent 86120C simultaneously measures multiple laser lines, you can characterize wavelength- division-multiplexed (WDM) systems and the multiple lines of Fabry-Perot lasers.
