Segmented active optics is a new design concept for making a lightweight optically stable primary reflector for large optical telescopes and especially for space telescopes. The concept applied to a threesegment 20-inch primary mirror has been proven feasible in laboratory experiments. Test results showed diffraction-limited performance with automatic optical figure control to better than L/50 rms.
