Preliminary Optical and Mechanical Designs for a 2.2 Degree Diameter PrimeFocus Corrector for the Blanco 4 Meter Telescope
Abstract
We describe a five element corrector for the prime focus of the 4 meter Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO) in Chile that will be used in conjunction with a new mosaic CCD camera as part of the proposed Dark Energy Survey (DES). The corrector is designed to provide a flat focal plane and good images in the SDSS g, r, i, and z filters. The mechanical design allows for full five-axis motion. We describe the performance in conjunction with the scientific requirements of the DES.
