ABSTRACT:
Augmented magic sphere rotator permanent magnetic structures are provided by augmenting a magic sphere augmented with an interior magnet that attains significant decreases in mass, bulk and length of the optically active element. Also provided is a multiple augmented magic sphere rotator permanent magnetic structure with two augmented magic spheres positioned in tandem that provides an advantageously significant reduction in mass. The augmented magic sphere rotator permanent magnetic structures of the present invention provide the desirable advantages of specifically decreased mass and bulk of the structure and decreased total length of the optically active elements. The augmented magic sphere rotator permanent magnetic structure and multiple augmented magic sphere rotator permanent magnetic structure can be used as Faraday rotator structures.
