Abstract
A new generation of optical telescopes is on the drawing board. These will be true giants with primary mirrors having a diameter of up to 100 metres. The technology that will enable this revolution to take place was developed at the W. M. Keck Observatory in Hawaii, where the world´s largest segmented mirrors are in daily use. This article looks at how the W. M. Keck Observatory proved the mirror technology that will be behind this new generation of telescopes
