Optical alignment of the Far-Ultraviolet Spectroscopic Explorer (FUSE)

The FUSE, scheduled for a summer 1999 launch, is an astrophysics satellite designed to provide high spectral resolving power over the interval 90.5-118.7 nm. The FUSE optical path consists of four co-aligned, normal incidence, off-axis parabolic primary mirrors which illuminate separate Rowland circle spectrograph channels equipped with holographic gratings and delay line microchannel plate detectors. The spectrograph comprises the upper half of the instrument structure, and was internally aligned prior to delivery to the integration team.
