Methods and devices incorporating wideband Faraday Rotation in which light having mixed wavelengths is dispensed according to wavelength and passed through a magnetic optical rotator along pathways of different lengths progressively and inversely with respect to wavelength so that shorter wavelengths travel proportionally longer pathways than longer wavelengths sufficiently that the angle of rotation is substantially equal for all wavelengths within the waveband.

[ We claim:] [15.] A device for wideband magneto-optical rotation of a polarization state of incident light comprising:(a) means for dispersing light according to wavelength in a waveband;(b) magneto-optical means for said rotation comprising an optical element having a surface for receiving incident light, said element being in light intercepting relation to the light emitting from the dispersing means such that the emitting light is incident on said surface; and(c) means for adjustably positioning the magneto-optical means element surface at an angle to the pathways of dispersed light, said angle corresponding to the wavelength of the light on said surface such that the shorter wavelength pathways through the magneto-optical means are longer than pathways for longer wavelengths sufficiently that the angle of rotation in the magneto-optical means is substantially equal for all wavelengths within the given waveband according to the adjusted angle of said surface to the corresponding wavelength.
