Abstract

Large area CCDs are not in general flat. Deviations from flatness are often greater than that allowed for the focal plane of moderately fast optical systems. We will discuss a technique of vacuum packaging that has allowed CCDs to be packaged with a flatness of better than five microns over a scale of greater than three centimeters. In principle this technique could be used to package a CCD so that the surface has a specific radius of curvature rather than a planar figure (infinite radius). 1.
