Abstract
Methods and systems for providing electromagnetic protection of optical equipment are disclosed. One assembly includes an optical device and an electromagnetically shielding enclosure including a plurality of shielding surfaces, the enclosure defining an interior volume containing the optical device. The assembly further includes a waveguide beyond cutoff extending through a shielding surface of the electromagnetically shielding enclosure. The assembly also includes a first lens located on a first side of the shielding surface, and positioned and oriented to focus light through the waveguide beyond cutoff. The assembly further includes a second lens located on a second side of the shielding surface opposite the first side, positioned and oriented to receive light transmitted through the waveguide beyond cutoff.
