Introduction to the Application of Spectrometers

In the world of Harry Potter, the spell "prank over" and a click on a wand can reveal the hidden map. In real life, the imaging technology of Duke University Library in the United States can also reproduce rotten text. Multi spectral imaging (MSI) can capture images under different colors of light, revealing details that cannot be seen by the human eye or standard high-resolution cameras. The working principle of multispectral imaging is to capture images under various colors of light throughout the entire spectral range, including some light that humans cannot see, such as ultraviolet and infrared. Spectrometer technology can revive historical relics, and together with the footprints of historical reproduction technology, we can understand the past world.

Tong Xudong, Chief Designer of High Score Special Projects and Director of the Major Special Projects Center of the National Defense Science and Industry Bureau, once said that different elements and compounds on Earth have their own spectral characteristics. Therefore, spectra are regarded as the "fingerprint" for identifying substances, used to identify and analyze the characteristics of different objects. Unlike the previous use of ordinary optical imaging, the Gaofen-5 satellite can detect the specific composition of substances through high-precision spectral analysis. The spectral resolution of this satellite enables full spectrum observation from ultraviolet to infrared, helping people to grasp the spatial distribution and concentration of atmospheric pollutants at the spatial scale.

With the continuous innovation and development of spectroscopic technology, spectroscopic instruments have gradually penetrated into various industries. In recent years, high-quality glasses have become the pursuit of many eyewear enthusiasts. However, for this complex and price difference lens market, it is confusing and difficult to choose. At this time, spectrometer detection technology can be used to distinguish the authenticity of resin lenses, and this application can be used to accurately identify and distinguish the quality of processed and assembled resin lenses in the market without damaging the lenses. Spectrometer detection technology can detect gases, liquids, and solids, and is almost an all-around technology.

According to Myers Consulting, a study led by Georgia State University and the University of Georgia shows that scientists can use the nano infrared spectral imaging technology to reveal the key structural changes of enveloped viruses such as AIDS virus, Ebola virus and influenza virus before invading host cells.

Spectrometers are widely used in fields such as agriculture, astronomy, automotive, biology, chemistry, coating, chromaticity measurement, environmental testing, film industry, food, printing, papermaking, Raman spectroscopy, semiconductor industry, component detection, color mixing and matching, biomedical applications, fluorescence measurement, gemstone component detection, oxygen concentration sensors, vacuum chamber coating process monitoring, film thickness measurement, LED measurement, emission spectrum measurement, etc UV/visible absorption spectroscopy measurement, color measurement, and so on. It can be seen that technology drives the development of society, and technology itself serves humanity. With the continuous deepening of development and research, spectrometer technology is combined with human health development, continuously benefiting society.
