The Detector Systems of the Keck Observatory: UV to 25 Microns

We provide an overview of the Keck Observatory, its instrumentation, detector systems, and plans for new instruments and detector upgrades. Even though the Keck instrumentation is older than that of the new 8 meter telescopes, in several cases the Keck detector systems are leaders in their class. However, in winning the race for the first very large telescope, the Keck Observatory has paid a price in terms of performance, lack of standardization and difficulty in maintenance. We discuss these challenges and our plans and dreams for ensuring that the Keck Observatory has the detector systems needed to stay at the forefront of astronomy.
