Abstract
A lens for utilization in the radiation energy exit port of a radiation energy integrating sphere is provided, and functions to prevent instrumental specular radiation energy reflections from striking the interior wall surfaces of the sphere and being collected thereby. The instrumental specular radiation energy reflections include those from the lens, per se, and those from instrumentation disposed without the integrating sphere.
