Beer–Lambert Law calculator

Transmittance through an absorbing medium.

Category: Photonics

Formula: T = 10^(-α·L·c)

Inputs

InputParameterUnitDefault
α (abs.)aL/mol·cm1000
PathLcm1
Conc.cmol/L0.001

Result with the default inputs

  • Absorbance A: 1
  • Transmittance: 10 %
  • OD: 1

Open it with your own values: put each input in the address as a parameter, for example /calculators/beer-lambert-law?a=1000. A unit other than the listed one goes in <parameter>_unit.
