<p>NEW AND IMPROVED LENS MEANS FOR USE IN RADIATION ENERGY INTEGRATING SPHERES Lens means for utilization in the radiation energy exit port of a radiation energy integrating sphere are provided, and function 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 means, per se, and those from instrumentation disposed without the integrating sphere.</p> |
