ABSTRACT:
A compound parabolic concentrator which can be used as an optical connector or in a like management system or simply as a concentrator or even as a spotlight, has a hollow body formed with an input aperture and an output aperture and a wall connecting the input aperture with the output aperture and diverting from the smaller of the cross sectional areas to the larger cross sectional areas of the apertures. The wall is composed of contiguous elongated prisms of a transparent dielectric material so that the single reflection from the inlet aperture to the outlet aperture takes place within the prisms and thus the losses of purely reflective reflectors can be avoided.
