Paper Abstract

The Coronal Diagnostic Spectrometer (CDS) is one of the key instruments of the ESA cornerstone mission SOHO, scheduled for launch in 1995. It is designed to study the solar corona in the EUV. After successful completion of an engineering model in 1991 the flight model fabrication was started end of 1992. In August 1993 the optical alignment of the CDS flight mirror (FM) module was completed. The paper reports about the fabrication and achieved quality of the primary and secondary mirrors as well as the alignment of the mirror system. The predicted optical quality (half energy width) of the whole telescope is HEW <EQ 3 arcsecs for spatial wavelength >= 10 mm and <EQ 6 arcsec for (lambda) >= 3 mm (2).
