Description: A spectrometer is an analytical instrument designed to measure and analyze the properties of light (or other types of electromagnetic radiation) as a function of its wavelength or frequency. The term "spectrometer" broadly applies to a range of instruments that can be used in different parts of the electromagnetic spectrum, including ultraviolet (UV), visible, infrared (IR), and even X-rays.
Function: The primary function of a spectrometer is to analyze the properties of light as a function of its wavelength. Spectrometers are used for a variety of purposes
