A spectrometer is an instrument used for analyzing spectra and can be used to study and measure phenomena caused by light. It can separate light waves into lights of different wavelengths through the action of beam - splitting, and conduct quantitative or qualitative analysis at the positions of lights of different wavelengths. The working principle of a spectrometer is based on the common principle of spectroscopy, that is, splitting a beam of light into lights of different wavelengths.
Spectrometers have a wide range of application fields, such as chemistry, physics, astronomy, geology, biology, and medicine. They are widely used in material analysis, pollution detection, food quality inspection, drug research, and other fields. With the development of technology, spectrometers have also gradually made progress in portability and intelligence, making the analysis operation process more convenient and simplified.
Its main components are an inlet and an outlet. The inlet is mainly responsible for receiving light input, and the outlet outputs the separated spectra. The output results of the spectrometer can be stored, processed, and analyzed in a digital way to obtain the corresponding spectral results.
