Abstract

The performances of a CCD have been evaluated in a very wide spectral region, which comprises near IR, visible, near and far UV, EUV and soft x-ray spectral regions. The CCD detector is a back illuminated one, 512 by 512 format, 24 by 24 micrometer squared pixel. The performed measurements consist mainly on the determination of the quantum efficiency in the 0.3 - 1100 nm (4.5 keV - 1 eV) spectral region. Three different experimental setup have been used: a Czerny-Turner monochromator for the 1100 - 250 nm region, a Johnson-Onaka monochromator for the 250 - 30 nm region, and a grazing incidence Rowland monochromator for the 25 - 0.3 nm region. The tested CCD exhibits high values of quantum efficiency in the analyzed spectral range, representing a very useful detector of radiation in the extended optical domain.
