In this paper, we calculate optimal prism configurations for achromatic N-prism beam expanders of a single material; we argue that for moderate to high magnifications, that is M> or approx. =(2-1/(2/sup N/-1-1))/sup N/, the up-up . . . up--down configuration is generally optimal, in the sense that it maximizes the transmission for given magnification. We also derive exact expressions for the incidence and apex angles that optimize a nonachromatic N-prism beam expander of arbitrary materials. The use of simple three-prism (up--up--down) and four-prism (up--up--up--down) single-material achromatic beam expanders is suggested for applications requiring compactness, achromaticity, and temperature stability.
