Abstract

As part of an ongoing effort to develop sensitive, high resolution spectrographs for the EUV and Soft X-rays we have been performing laboratory evaluation of novel spectrograph designs. We will discuss the measured performance levels of three systems: 1) A "hybrid" grazing incidence echelle spectrograph; 2) a Radial-Groove Grating Spectrograph; and 3) An Objective Reflection Grating Spectrograph for X-ray Astronomy. These systems show the great potential that conical diffraction spectrographs hold for the future.
