The Thorlabs OSA207C Optical Spectrum Analyzer is a general-purpose instrument that measures optical power as a function of wavelength. It has a user friendly Graphical User Interface and can be controlled from a standard PC via High Speed USB 2.0 port. It is a Fourier Transform Optical Spectrum Analyzer (FT-OSA), which utilizes a scanning Michelson Interferometer in a push/pull configuration. This approach allows for the design of a full-featured OSA with the additional benefit of a high precision Wavelength Meter. Specifications.
