Abstract

The UV and EUV instruments designed for the ESA/NASA Solar and Heliospheric Observatory (SOHO) are described, and their characteristics are presented. The SOHO instruments include the SUMER telescope for measuring line profiles and images in the wavelength range 500-1600 A, with a 1.5-arcsec resolution; the Coronal Diagnostics Spectrometer for measuring line ratios and images in the range 170-800 A, with a 2 arcsec resolution; a EUV imaging telescope for producing narrow band pass images in the spectral lines at 171 A, 195 A, 195 A, 284 A, and 304 A, with a 3-arcsec resolution; a UV coronagraph spectrometer for measuring line profiles and images of EUV lines from about 500 A to about 1200 A, with a several arcsec rosolution; and the SWAN, a lens with hydrogen absorption cell for measuring Ly-alpha profiles in the far corona and heliosphere.
