Fabrication of optical components for the ultraviolet spectrometer and polarimeter on the Solar Maximum Mission
The Solar Maximum Mission (SMM) satellite was launched in February 1980 into a 573 km high circular orbit. It contains X-ray, UV, and optical instruments for the simultaneous observation of solar flares. The ultraviolet spectrometer and polarimeter (UVSP) is one of these instruments. The objectives of the UVSP require the employment of a raster scanning telescope to study the spatial dynamics of flares, the use of a high resolution spectrometer to select and scan spectral lines for temperature and velocity diagnostics, and the utilization of a polarimeter to measure magnetic fields in the solar transition zone. The present paper has the objective to provide a description of the optical fabrication techniques developed for the instrument. Attention is given to telescope mirrors, metering rods, the Ebert mirror, grating blanks, a four-mirror polarizer, beam splitter assemblies, beam splitter fabrication, deflector mirrors, and shipping containers.
