Abstract

A technique is described for measuring near-axis scatter of infrared (10.6 μm) energy from high-reflectivity metal mirrors. Typical scatter data are presented for several samples. The data are applicable to optical instruments such as the Lyot Coronagraph. The measurement apparatus is described in detail. Surface roughness and contamination are considered. The preparation of the surfaces is discussed in detail.
