Abstract

The solar EUV spectrometer SUMER will operate in the wavelength range 500 angstrom to 1600 angstrom on the SOHO spacecraft. It will allow measurements of profiles, Doppler shifts, and intensities of solar extreme ultraviolet lines. Various mechanisms for pointing and focusing of the optical components contribute to the versatility of the instrument. The normal incidence optical design of the telescope and the spectrometer puts very stringent constraints on the cleanliness of the instrument and the mechanical design. The calibration techniques used, including imaging tests in the EUV, wavelength, and radiometric calibrations are outlined, and performance predictions are given.
