A = \log (\frac{P_{0}}{P})

$A = log((P_0)/(P))$

(P) Irradiance

$(P)"Irradiance"$

(P_{0}) Initial irradiance

$(P_0)"Initial irradiance"$

where

P₀ is initial irradiance (or intensity of light) from wavelength selector to sample in units of (Energy/sec*area of light beam)
P is the irradiance from sample to the light detector in units of (Energy/sec*area of light beam)
A is absorbance
