IdealPhotonics' polarimeter is an optical instrument used to accurately measure the polarization state of light waves (such as degree of polarization and polarization angle) or the polarization characteristics of materials. Its core function is to quantitatively analyze the amplitude, phase, and direction changes of polarized light.High-precision polarization state measurement (Stokes parameters/polarization angle), wide wavelength coverage, suitable for liquid crystal detection, optical thin film analysis, and research on the polarization properties of materials.
