th The four ESO CCO Workshop, Optical Detectors for Astronomy, was once held in the course of September 13-16, 1999 at its traditional position, the headquarters of the ecu Southern Observatory in Garching, Germany. We like to take note this workshop as a "meeting of friends", who got here to Garching to go to ESO and to give their paintings, instead of a proper assembly. in line with our event with the 1996 ESO CCO workshop, we intentionally positioned emphasis on growing an atmosphere that inspired the members to stick jointly and informally alternate principles. those casual occasions started with a journey of the BWM vehicle manufacturing facility and persisted with a reception at "SchloB Beletic", the convention dinner at a true SchloB of the Bavarian foreign university (where the contributors loved basket, baseball, desk football, mountaineering and finally dancing) and concluded with a travel of the Paulaner Brewery and dinner on the Seehaus within the Englisher Garten. The lunch "Biergarten", adjoining to the poster consultation quarter, used to be an everyday assembly aspect. the outcome was once an outstanding mix of first-class shows and posters, accumulated in those court cases, and plenty of events for individuals to get involved and to have a good time jointly, as witnessed by means of the choice of workshop photos that we randomly put among papers. This e-book incorporates a specified contribution.
