Telecommunication systems - semiconductors and optical fibers - require speed, accuracy and high quality. Glass is the key. Newly developed glass is both durable and scratch resistant. It is also used for terrestrial and extra-terrestrial telescopes. For example, The Very Large Telescope (VLT) in Chile uses four individual mirrors, each over eight meters in diameter, to see the details of our galaxy and beyond.
