Spectrometers categories

A spectrometer is a scientific instrument that decomposes light of complex composition into spectral lines and consists of a prism or diffraction grating. The spectrometer can measure the light reflected from the surface of an object. Its basic function is to measure the spectral characteristics of the studied light (reflected, absorbed, scattered or excited by the studied substance, etc.), including spectral characteristics such as wavelength and intensity.
According to the working principle of the spectroscopic instrument, they can be divided into two categories: one is a classical spectrometer based on spatial dispersion and interference spectroscopy; the other is a new spectrometer based on the principle of modulation. According to different dispersive elements can be divided into prism spectrometer, grating spectrometer and interference spectrometer.
Light sources and lighting systems can be the subject of research and can also be used as research tools to illuminate the material being studied. In general, the light source is the object of study when studying emission spectra of substances such as gas flames, AC/DC arcs, and sparks; however, when studying absorption, Raman, or fluorescence, the light source is used as the illumination. Tools (such as mercury lamps, infrared drying lamps, UFO lamps, Xenon lamps, LEDs, lasers, etc.).
Applications: Spectrometers are widely used in industry (eg automotive, coating, food, paper, semiconductor industry, color mixing and matching, film thickness measurement, oxygen concentration sensor and vacuum chamber coating process monitoring, etc.) Agriculture, astronomy, biology , chemistry, colorimetric metrology, environmental testing, Raman spectroscopy, composition detection, biomedical applications, fluorescence measurement, gem composition detection, LED measurement, emission spectrometry, UV/Visible absorption spectroscopy, color measurement, and more.
The GLA600-UVN fiber optic spectrometer manufactured by Gaolitong Technology (Shenzhen) Co., Ltd. adopts a Czerny-Turner optical structure, uses a grating as a light separating element, uses a CCD as a photodetector, and an optical signal can be introduced by an SMA905 fiber connector. The GLA600-UVN features wide spectrum, high spectral resolution and large dynamic range. The USB mini-B interface is connected to the computer, so that the spectrometer can be directly controlled and powered by the computer, and its small size and beautiful appearance.
The software developed by the company for the GLA600-UVN fiber spectrometer is easy to operate, with automatic configuration of the spectrometer, automatic reading of spectrometer calibration coefficients, spectrum acquisition and measurement, log and color bar display functions. The software interface intuitively displays the spectral curve of the wavelength and intensity, which can zoom in to observe the more subtle fluctuations of the spectrum and the peak size. At the same time, the spectral curve of Pixel-Intensity can be switched. Spectral measurement functions include radiation measurements, transmittance measurements, absorbance measurements, and reflectance measurements.
