Abstract
The design of averaging spheres without internal target is described. The performance of such spheres is analyzed theoretically and tested experimentally. In a final design, an efficiency of 40% is achieved for visible and near-uv wavelengths. The averaging effectiveness is characterized by signal variations of the order of 1 part in 104 for beam displacements of several 0.1 mm.Keywords
