1. Product introduction

The Beer-Lambert Law states that the proportion of light absorbed by a transparent medium is independent of the intensity of the incident light; each equally thick medium absorbs the same proportion of light on the optical path. It is the third law of photochemistry. is the fundamental law of light absorption and applies to all electromagnetic radiation and all light-absorbing substances, including gases, solids, liquids, molecules, atoms, and ions. The Beer-Lambert law is the quantitative basis for absorptiometry, colorimetric analysis, and photoelectric colorimetry. The amount of light absorbed is proportional to the number of molecules in the optical path that absorb light.
