Abstract

This detector system was designed primarily for spectroscopic applications in astronomy. The main design goal was to provide a fast, high throughput optical system for adapting cryogenically cooled, self-scanned solid-state arrays to an existing KPNO spectrograph. The final system design combined the optics, mechanical housing, cryogenic cooling, detector, and the first stage of detector electronics into a single package. The system includes an F/7.6 collimator, grisms (prism and transmission grating combined), an F/1.0 Schmidt-type optical camera, a cryogenically cooled, high resolution, solid-state CCD array with a specially designed electronics package for the detector. The system was optically and mechanically interfaced to an existing KPNO spectrograph for added flexibility and cost savings. The system can, with minimum reconfiguration, be used for slit spectroscopy, two-dimensional slitless spectroscopy, or two-dimensional photometry. The spectroscopic applications can be configured for low resolution use with a transmission grism or for medium resolution use with a reflection grating.
