Abstract
A portion of a nearly spherical reflector is used to direct the electromagnetic radiation onto a small target. The electromagnetic radiation source is displaced from the optical axis of the reflector to maximize flux density at the target with minimal distortion. The present invention is particularly suited to coupling light from an arc lamp into an optic fiber.
