Request InfoGeneral Photonics Corp.General Photonics Corp. has announced a new version of its PolaWise polarization measurement system, which characterizes all polarization-related properties of light sources and optical materials, including state of polarization, degree of polarization, polarization mode dispersion (PMD), polarization-dependent loss (PDL) and polarization extinction ratio (PER). It repeatably measures PMD in the femtosecond range. Previously, it was available only for the 1440- to 1620-nm wavelength range; the new model covers the 1280- to 1340-nm range.
