Principle of Handheld Spectrometer
Handheld spectrometers operate on the principle of spectrometry, where the emitted, absorbed, or reflected light from a sample is measured. These devices utilize the interaction between light and matter to identify and quantify various chemical compounds. They take light, separate it by wavelength and create a spectrum which shows the relative intensity of these separate wavelengths. A mass. A spectrophotometer assists in finding the amount of light an object absorbs at a given wavelength.
