» Shaping thin glass mirrors using air bearings
Presentation duration: 15 minutes
Presenter: Mark Schattenburg
Thermal shaping of glass against precision mandrels is a promising technology for producing x-ray mirrors for future missions such as the International X-Ray Observatory (IXO). While a great deal of progress has recently been made to improve the accuracy of slumped glass mirrors, high-frequency ripples are still difficult to control, due primarily to problems with sticking and dust particles. In this talk we describe a new technology for shaping hot glass between pairs of precision porous ceramic air bearings which eliminates sticking and dust particle problems.
