Paper Abstract

Soft x-ray telescopes require filters that block visible and infrared light and have good soft x-ray transmission. The optical properties of possible materials are discussed, and the fabrication and testing methods for the filters used in a 10-inch normal incidence telescope for λ = 63 Å are described. The best performances in the λ 44—114 Å wavelength range are obtained with foils of carbon and rhodium.
