Micro-roughness improvement of slumped glass foils for x-ray telescopes via dip coating
Abstract
The large effective area requirement for future X-ray telescopes demands the production of thousands of segments made of a light material, shaped and integrated into the final optics. At INAF/Osservatorio Astronomico di Brera we developed a direct hot slumping technique assisted by pressure, to replicate the shape of a mould onto the optical surface of a glass mirror segment. To date, the best results were achieved with a mould in Zerodur K20 and glass foils made of aluminumborosilicate glass type AF32 by Schott. Nevertheless, several factors in the fabrication process trigger deviations from the desired surface micro-roughness. A dip-coating technique is investigated to improve the surface smoothness and consequently the imaging properties of the mirror. In this paper we describe the coating technique, the different implemented processes and the results obtained....
