Researchers in Japan developed a desktop prototype magneto-optic effect measurement device capable of evaluating the characteristics of magnetic materials with improved optical system and signal detection system its measurement performance greatly exceeds conventional measurement methods. It has magneto-optic effect measurement resolution of 0.01 degree, a wavelength resolution of 0.01 nanometer and capable of high-speed measurement through batch measurements of all wavelength components. A major feature of the prototype is its capability to measure the phase difference of light in addition to its intensity ratio. It is expected to become an important new tool for the precise measurement of polarization and spectroscopy, and for the material development…read more.
