Preliminary engineering studies are in progress to define a telescope for the Far Ultraviolet Spectroscopic Explorer (FUSE) mission. General science objectives include high resolution spectroscopy in the 900A to 1200A region, low or moderate resolution spectroscopy in the 100A to 900A range, and limited long slit imaging at a spatial resolution of one arcsecond. Telescope design studies indicate that a one meter diameter Wolter-Schwarzschild type II glancing incidence telescope with an effective collecting area of 3000 square cm is required to meet the primary science objectives. A baseline optical design has been completed, and initial alignment sensitivities derived to begin the process of error allocation for the entire system. Various mirror fabrication methods are under evaluation, and include the incorporation of contemporary diamond turning technology with small tool computer controlled polishing.
