Brief description：A UV-Visible spectrophotometer is an analytical instrument based on the principle of UV-Visible spectrophotometry, which analyzes substances by using the absorption of ultraviolet and visible light by molecules. A molecule's UV-Visible absorption spectrum is created when certain groups within the molecule absorb UV-Visible radiation, causing electronic energy level transitions that produce the absorption spectrum. Since different substances have unique molecules, atoms, and molecular structures, the energies at which they absorb light differ. Therefore, each substance has its own characteristic, fixed absorption spectrum. By looking at the absorbance at certain characteristic wavelengths on the spectrum, you can identify or measure the amount of that substance.

Industry Applications：Qualitative and quantitative analysis, evaluation of optical properties (transmission, reflection, haze, color, etc.).
