Charge Transfer Devices in Spectroscopy Jonathan V. Sweedler, Kenneth L. Ratzlaff, and M. Bonner Denton, Eds. VCH 220 East 23rd Street New York, NY 10010-4606 1994, 406 pp., $95
This book is the best available source for detailed information on the operation and spectroscopic applications of chargecoupled device (CCD) and charge injection device (CID) detectors. These charge transfer devices (CTDs) are now used in both the research laboratory and, more and more commonly, as integral parts of commercial instruments. The authors were among the first to use solid-state detectors for spectroscopy, and as a result, they have a great deal of insight into how the devices operate, advantages and limitations of the different detectors, and how to choose the appropriate detector for a particular experiment. Many of the 10 chapters can be read as stand-alone treatises on particular topics. There is some overlap among chapters (not surprising for a book written by 10 authors), but it enhances reading of single chapters. The overlap is not so extensive as to be distracting if the book is read cover to cover. The book effectively brings together information on charge transfer devices into one comprehensive source. For example, different CCD architectures in commercial devices are described, specialized readout modes are covered, and the implications of the properties of silicon, backside illumination, and phosphor coating are discussed. Multipinned phase-type 246 A
CCDs, which result in lower dark current, are also discussed. Detectors designed for X-ray, IR, visible, and UV regions of the spectrum are all nicely considered, and means to correct for pixel-to-pixel sensitivity variations are described. Commercial sources for CTDs are also listed. A useful chapter on intensified CTDs provides information, considerations, and examples of quantitative calculations necessary to decide whether or not to use an intensified CTD and iffiberoptic coupling or lens coupling is most appropriate. The chapters describing the applications of CTDs for planar separations, multichannel Raman, luminescence, plasma diagnostics, and atomic emission spectroscopy are all well written. Each chapter
Overall, this is an outstanding book. The authors and editors have assembled a tremendous amount of useful and important information on charge transfer devices into a single book.
