20090215605 | Process of producing a glass-ceramic, the glass-ceramic made therby and its uses - The process of making the glass-ceramic includes ceramicizing a starting glass at a heating or cooling rate during the ceramicization of at least 10 K/min, so that the glass-ceramic contains at least 50% by volume of ferroelectric crystallites with a maximum diameter of from 20 to 100 nm and not more than 10% by volume of nonferroelectric crystallitesis. The glass ceramic produced by the process contains no pores or not more than 0.01% by volume of the pores and a value of e′·V | 08-27-2009 |
20090279068 | Device and process for increasing the light transmission of optical elements for light having a wavelength close to the absorption edge - Described are a process and a device for increasing the light transmission of an optical element for light of a wavelength that is close to the absorption edge of the material constituting the optical element. The process involves cooling the optical element. The process is especially well suited for microlithography with immersion objectives. A preferred device is, for example, a stepper for producing electronic components. | 11-12-2009 |
