Paper Abstract

We have been performing design and optimization of the optics for the Wide Field Spectrometer (WFS): one of the core instruments of the EDGE mission whose science targets are the studies of formation and evolution of large scale structures in the universe. WFS mirrors are based on a conical approximation of the Wolter-I design fabrication technique already applied for ASCA and SUZAKU satellites. In order to give both a large effective area and grasp with small TES detector we use a very short focal length with 1.2 m and 4 reflections system for the outer diameter. The effective area and grasp including the detector efficiency and the filter transmission are 1163 cm2 and 405 cm2deg2 at 0.6 keV respectively.
