Abstract
The present invention comprises a system for condensing and collecting electromagnetic radiation having a primary reflector disposed on one side of an electromagnetic radiation source and a target disposed on the opposite side of the source. The primary reflector includes a concave reflecting surface portion, which preferably forms the entire surface of the reflector. The concave surface portion of the primary reflector, which is preferably of a substantially toroidal shape, defines an optical axis and a primary center of curvature disposed along the optical axis. The source of electromagnetic radiation is located approximately on the optical axis but axially offset a first distance from the center of curvature in a direction toward the concave surface portion. The target, such as a single core fiber optic or a fiber optic bundle, is located approximately on the optical axis but axially offset a second distance from the center of curvature in a direction away from the concave surface portion for acquiring a substantially focused image of the source reflected by the concave surface portion. With this configuration, the first and second distances are approximately related by the equa…
