Description: 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 pision multiplexed) signals and multiple lines of Fabry-Perot
lasers. Each laser line is assumed to have a linewidth of less than 10 GHz.

This unit has the following specifications:
