The SOAR Optical Imager (SOI) is the commissioning instrument for the 4.2-m SOAR telescope, which is sited on Cerro Pachón, and due for first light in April 2003. It is being built at Cerro Tololo Inter-American Observatory, and is one of a suite of first-light instruments being provided by the four SOAR partners (NOAO, Brazil, University of North Carolina, Michigan State University). The instrument is designed to produce precision photometry and to fully exploit the expected superb image quality of the SOAR telescope, over a 6x6 arcmin field. Design goals include maintaining high throughput down to the atmospheric cut-off, and close reproduction of photometric passbands throughout 310-1050nm. The focal plane consists of a two-CCD mosaic of 2Kx4K Lincoln Labs CCDs, following an atmospheric dispersion corrector, focal reducer, and tip-tilt sensor. Control and data handling are within the LabVIEW-Linux environment used throughout the SOAR Project.

Additional Information:© 2003 Society of Photo-Optical Instrumentation Engineers (SPIE). We would like to thank Thomas Ingerson, Roger Smith, and Gilberto Moretto for important contributions to the SOI design. Gerald Cecil and Steve Heathcote, in their respective capacities of SOAR Project Scientist and SOAR Director have provided sage advice. CTIO draftsmen, technicians and instrument makers are thanked for their skill and dedication, without which this instrument could not have been turned from design into reality. Victor Krabbedam, SOAR Project Engineer, and Michael Warner, Systems Engineer, have dealt with telescope interface issues in timely manner.
