APEX Technologies presents you a new option for an Optical Spectrum and Polarization analysis. By adding this option to our High Resolution OSA, the state of polarization can be measured. This measurement can be integrated over the full wavelength range of the polarimeter or as a function of wavelength. Two different displaying modes exist: Jones graph and Poincaré sphere. Different detection modes are available: peak mode, area mode, point mode, threshold mode, markers mode. The evolution of the state of polarization can be measured as a function of time, and as a function of wavelength.
