Spectroscopy denotes the process of assessing how an object absorbs or gives off light. Raman Spectroscopy also involves the analysis of how different chemicals disperse or spread light into many different wavelengths, separating it into multiple colors.
Because all objects absorb or emit light, scientists can collect information about a compound’s properties by simply analyzing what sort of light is absorbed or emitted. In actuality, even the temperature and mass of an object can be measured using spectroscopy.
Near-infrared spectroscopy is a type of spectroscopy that scans a thing or compound using the near infrared portion of the electromagnetic spectrum, which is essentially light with wavelengths ranging from 800 to 2500 nanometers. By quantifying the pattern of near-infrared light reflected by a certain sample, NIR spectroscopy can provide information regarding its chemical composition.
The near-infrared technology uses a light source to offer light that will bounce off the sample. A light-dispersing object, such as a prism, divides the light into different wavelengths. The near-infrared wavelengths are detected and place into the record to present an appropriate analysis of this sample.
Near-infrared spectroscopy provides some advantages over other types of spectroscopy. Since the signal to noise ratio of NIR technology is great, background readings, which could affect the accuracy of a scan, are lower than those of sample test results. Lower noise levels help doctors and scientists get clearer, more accurate results from near-infrared reflectance tests.
Another significant advantage of NIR spectroscopy is its affordability. Individuals may conduct extensive spectroscopic analysis at a relatively affordable price in comparison to MRI scanning and other spectroscopic techniques. uRaman-Ci is a complete Raman micro spectroscopy system .

Moreover, near-infrared light can penetrate a lot deeper than infrared light, so scanning objects and substances at a much larger scale is possible with near-infrared reflectance.
