Abstract : This article is the first in a two-part series describing charge transfer devices (CTDs) -- a relatively new class of multichannel detectors for the ultraviolet to near-infrared spectral regions. An overview of the operation and the characteristics of CTDs relevant to analytical spectroscopy is presented. The sensitivity and dynamic range obtainable from CTD detectors are discussed and compared to the sensitivity and dynamic range obtainable from other spectroscopic detectors. Unique capabilities such as the ability to nondestructively readout the detector array and the ability to alter the effective detector element size using the process of binning are described. Detector array formats ranging from single elements to extremely large arrays, large photoactive areas, high quantum efficiencies, dark count rates allowing long integration times and low read noises all contribute to the outstanding performance and great flexibility offered by CTDs.
