Abstract

Scatter from Beryllium mirrors often seems to be higher than would be expected based on mirror surface roughness data. This paper verifies the effect and shows that it is more severe in the IR than in the visible. The implication is that the excess scatter is caused by mirror defects that are non-topographic in nature. The conclusion is that profile, or roughness specifications should not be used when low scatter is the requirement of concern.
