Abstract
An apparatus for measuring magneto-optical effect includes a light source 102, a spectroscope 120, a first polarizer 150 to polarize the light with a required wavelength taken out by the spectroscope 120, means 172 for applying magnetic field on a sample 176, a second polarizer 156 to admit the light transmitted or reflected by a sample 176 to pass, a photo-detector 162 for detecting intensity of light that has passed the second polarizer 156. The light source 102 includes a heavy hydrogen lamp and the spectroscope does not contain a lens and/or prism. A light path from the light source to the photo-detector is housed in a container, and the container is filled with a gas containing no oxygen.
