Agilent HP 86120B Multi-Wavelength Meter

The Agilent 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
