Researchers at the Fraunhofer Institute for Mechanics of Materials have developed and optimized the "hot embossing" technology for the manufacturing of glass lenses. Glass lenses can nowadays be found in cameras, automobile headlamps, and a variety of optical sensors. Today, the lenses are produced by "precision molding", whereby the glass is heated together with the forming die and then pressed into shape. The new technology is up to 10 times faster, a good 70 percent cheaper, and produces lenses of comparable quality...
