Absorbance to Transmittance Formula
The following formula is used to calculate the percent transmittance from absorbance.
%T = anti-log (2 – a)
- Where %T is the percent transmittance
- a is the absorbance
Absorbance to Transmittance Definition
Converting an absorbance to transmittance involves taking the antilog of 2 minus the absorbance.
Absorbance to Transmittance Example
