4mRC Camera & CCD
Only one camera and CCD combination is presently used with the R-C spectrograph: the Blue Air Schmidt (BAS) and Loral 3K CCD (L3K). The Air Schmidt camera is a field-flattened Schmidt camera of 229 mm focal length and 229 mm clear aperture (f/1). This camera is used exclusively with the Loral 3K CCD, which together with its special dewar, forms an integral part of the camera.
The demagnification with the BAS is a factor of 5.1 which results in a spatial scale of 0.50 arcsecond per 15micron pixel. The full field of view illuminated by the 50mm long slit is approximately 656 pixels or 328 arcseconds.
