Abstract
A terminator system particularly suited for beams of high intensity electromagnetic radiation such as from a laser includes an enclosure having a hole therein and a black mirror mounted in the enclosure. The black mirror has a specularly reflecting surface opposite the hole and is oriented at an angle such that the beam impinging on the hole would be impinging on the specularly reflecting surface and would not be reflected directly back out the hole. The black mirror is constructed of a material that absorbs energy at the wavelength of the incident beam. In another preferred embodiment, there are a plurality of black mirrors for performing a succession of reflections, so that the beam power is reduced significantly at each reflection.
