Paper Abstract

Quartzglass mirror blanks in the form of ultra lightweight structures offer distinct advantages, especially for cryogenic and space applications. As with all other substrate materials, however, generating and finishing of large aspherical surfaces is a costly and time consuming process. Heraeus Quarzschmelze has developed a technique which allows to produce quartzglass face sheet surfaces to nearly net shape by a precision hot forming process. Spherical and aspherical surface figures achieved with this process can be accurate to within some microns.
