HP 86120B Multi-Wavelength Meter

The HP 86120B Multi-Wavelength Meter is a Michelson interferometer-based instrument that measures wavelength and optical power of laser light in the 700 to 1650 nm wavelength range. Simultaneous measurements of multiple laser lines are performed allowing measurements of WDM (wavelength division multiplexed) signals and multiple lines of Fabry-Perot lasers.

[ Features ]

Multiple and average wavelengths measured
Peak and total powers measured
Automatic signal-to-noise ratios calculated
Power and wavelength of up to 100 channels
Built-in routines for channel spacing and drift
Accurate enough for use in the lab and rugged enough for use in the field
