Holdridge, D.

Many linear and circular lens designs were tested to verify both predicted and field test results. Analyzer test results confirm existing data on energy distribution, but yield lower lens efficiencies than expected. Approximately 15 to 20% of the energy exiting the lens is not being detected at the focal plane. It is thought that the chopped beam leaving the lens centerline and the periphery is resulting in a phase shift problem with the detector. Tests are in progress to determine and cure the test problems. Nearly all performance predictions for the three candidate lens designs were completed. These designs include: plano convex lenses; bi-convex lenses; and convex-concave lenses. (MHR)
