Optical Spectrum Analyzer-benchtop - The HP Agilent 86141B is a benchtop Optical Spectrum Analyzer(OSA) with a monochromator output and photodiode input.
The HP Agilent 86141B displays the amplitude of light versus wavelength over a 600 to 1700 nm wavelength range.
The unit uses a double-pass monochromator design to simultaneously achieve high sensitivity and dynamic range with a fast sweep time.
