Specialty spectrometers and accessories are specialty or proprietary products and accessories related to spectrometers, analytical instruments that are used measure the amount of dispersion of a property such as mass or energy. Like other types of spectrometers, specialty spectrometers are used to determine chemical composition and to perform electromagnetic radiation analysis by measuring light intensity across the visible, ultraviolet (UV), and infrared (IR) spectrums. A specialty spectrometer can be built using optical detectors such as charged coupled devices (CCD) or photo diode arrays, or fiber optics.
