Abstract
A Faraday-effect magneto-optic transducer provides for optimizing the transmission of light through the transducer. A transparent supporting assembly for a planar element of magneto-optic material includes first and second reflectors on opposing sides of the element. The reflectors direct polarized light through the element substantially normal to its interface with the supporting assembly, for preventing light loss due to internal reflections as light is transmitted through the supporting assembly and magneto-optic element.
