Microspectrometers, miniature spectrometers, portable spectrometers, or Fiber Optic Spectrometers are some of the names typically given to the class small spectrometers that are derived from simple, fixed optics, and low cost detector arrays. The author will use these terms interchangeably. This class of instrument has been available for over 18 years, gaining industry acceptance with each year. From a very basic optical platform to sophisticated instrumentation for scientific investigation and process control, this class of instrument has evolved substantially since its introduction to the market. For instance it is now possible to cover the range from 200 - 2,500 nm utilizing only two channels of spectrometers with either synchronous or asynchronous channel control. On board processing and memory have enabled the instruments to become fully automated, stand alone sensors communicating with their environment via analog, digital, USB2 and even wireless protocols. New detectors have entered the market enabling solutions "tuned" to the demands of specific applications.
