Beer-Lambert law Calculator

The Beer-Lambert law, also known as the Beer-Lambert-Bouguer law, relates the absorbance of light to the properties of the material through which the light is passing.

Where:

  • is the absorbance of the sample.
  • (epsilon) is the molar absorptivity or molar extinction coefficient, a constant characteristic of the substance at a particular wavelength.
  • is the concentration of the absorbing species in solution, typically measured in mol/L (molarity).
  • is the path length of the sample cell in centimeters, which is the distance the light travels through the sample.
