Ultraviolet detectors parallel

The ideal high-throughput analytical technique would be efficient in terms of required resources and would be scalable to accommodate an arbitrarily large number of samples. In addition, this scalability would be such that the dependence of the cost of the equipment to perform the experiments would scale in a less than linear manner as a function of the number of samples that could be studied. The only way to accomplish this is to have one or more aspects of the experimental setup utilize an array-based approach. Array detectors are massively multiplexed versions of single-element detectors composed of a rectangular grid of small detectors. The most commonly encountered examples are CCD cameras, which are used to acquire ultraviolet, visible and near-infrared (IR) photons in a parallel manner. Other examples include IR focal plane arrays (FPAs) for the collection of IR photons and channel electron multipliers for the collection of electrons. 

In its simplest form the exciting system will consist of a source, illumination optics, filter and polariser, and the intensity-measuring system will consist of an analyser, collection optics, filter and detector. The source of ultraviolet light is usually a mercury or xenon arc and the filter on the source side of the specimen selects from its output a narrow band of wavelengths near the peak of the absorption spectrum of the particular fluorescent molecule in use. The illumination optics should transmit the light as a fairly parallel beam to the specimen, so that it can be given a...
