Book Description
The operational characteristics of several new solid state array detectors investigated in our laboratories have shown themselves to be highly suitable for application in analytical spectroscopy. The devices investigated to date are selected charge-coupled devices (CCDs) and charge injection devices (CIDs), each of which has certain unique capabilities which can be exploited for solving a variety of spectroscopic problems. Readout speed considerations when using sequential, pseudo-random, random, binning, and rapid scanning readout modes will be discussed. Optoelectronic characteristics of these devices including dynamic range, quantum efficiency, noise, resistance to blooming and lag will be contrasted to photodiode arrays, vidicons, and photomultiplier tubes. Several optical configurations for array detector spectrometers which effectively utilize the various device geometries including the latest generation echelle configuration will be presented. Design considerations including resolution, spectral coverage, detector element size, stray light, and image reduction will be discussed. Keywords: Optical spectroscopy; Multichannel techniques; Charge transfer devices.
