Abstract

The present invention comprises a system for condensing and collecting electromagnetic radiation having a primary reflector (P, M1) disposed on one side of an electromagnetic radiation source and a target (T) disposed on the opposite side of the source (S). The primary reflector (P, M1) includes a concave reflecting surface portion, which preferably forms the entire surface of the reflector. The concave surface portion of the primary reflector (P, M1), which is preferably of a substantially toroidal shape, defines an optical axis and a primary center of curvature disposed along the optical axis (z). The source (S) of electromagnetic radiation is located approximately on the optical axis (z) but axially offset a first distance from the center of curvature in a direction toward the concave surface portion.
The target (T) i.e. a single core fiber optic (f) or a fiber optic bundle is located approximately on the optical axis (z) but axially offset a second distance from the center of curvature.
