Abstract

Grazing incidence telescopes are required for extreme ultraviolet astronomy (100 < < 1000 A) when observing at wavelengths shortward of 500A, and provide the highest throughput over the entire bandpass. Grazing incidence telescopes of conventional design have a substantial soft x-ray response as well as an extreme ultraviolet response. However, the available bandpass filters designed to transmit radiation longward of 400Å also transmit soft x-rays, which compromises the quality of the extreme ultraviolet data. We describe a grazing incidence telescope which is designed to suppress the soft x-ray throughput. This telescope incorporates a Wolter Schwarzschild Type II mirror with large graze angles. It retains all the desirable features of an extreme ultraviolet photometric survey telescope (high throughput, wide field of view, compactness) and, in addition, has no soft x-ray response. A telescope of this design will be flown on the Extreme Ultraviolet Explorer mission to make a survey of the sky at extreme ultraviolet wavelengths longer than 400Å.
