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 900 A to 1200A spectral region, low or moderate resolution spectroscopy in the 100 A to 900 A range, and long slit imaging over a 1 arcmin field at a spatial resolution of 1 arcsec. Telescope design studies indicate that a 1 m diameter Wolter-Schwarzschild type II glancing incidence telescope with an effective collecting area of 3000 cm2 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 being evaluated, including the incorporation of contemporary diamond turning technology with computer-controlled polishing.
