Spectrophotometry Calculators

Use the Beer-Lambert Law to calculate absorbance, concentration, and light transmittance in chemical solutions.

Beer–Lambert Law

Use this Beer–Lambert Law Calculator to compute light absorbance and transmittance of a solution based on its molar absorptivity, concentration, and path length. Ideal for students, chemists, and lab technicians, this tool simplifies spectrophotometric calculations using standard units.
