Abstract
A laser beam expander provides usable optical performance from 1800A to 12,000A and nearly diffraction-limited optical performance over a spectral range of 2400A to 11,000A without focus adjustment, and with a beam expansion ratio of 20 to 1. Four air-spaced all-spherical-surface lenses are arranged in two pairs in Galilean telescope type series. The first three lenses are biconcave and of fused silica and the fourth lens is biconvex and of calcium fluoride. Working and mounting tolerances are conventional.
