Abstract
This paper provides an overview of the status of ESO’s optical detector systems, reporting on progress made in the areas of CCD procurement, control electronics, cryostats and system integration. A strong effort at ESO in these areas during the past 5 years has resulted in CCD systems that are of the quality and quantity required by the world’s largest observatory. This work came to fruition in 1998-9 when 14 CCD systems using a total of 26 CCDs were delivered. The rate of CCD system deliveries has peaked and the pace will slow over the next few years, but most of the new systems will be mosaics of CCDs, the largest being the 16Kxl6K Omegacam system. At the end of 2002, ESO will have a total of 27 CCD systems running on 24 instruments; altogether 75 CCDs that total 575 million pixels.
