DEIMOS detector mosaic assembly

DEIMOS is a large multi-object spectrograph with an imaging mode that is being built for the W. M. Keck 2 Telescope. The detector is a 2 X 4 mosaic of eight 2048 X 4096 pixel CCDs. The mosaic assembly process must position the CCDs to be planar to within 5 microns rms. We describes the CCD support design and the measurements used to achieve this.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
