Maximum absorption
The term absorptionrefers to the physical process of absorbing light, while absorbance does not always measure only absorption; it may measure attenuation(of transmitted radiant power) caused by absorption, as well as reflection, scattering, and other physical processes. History and uses of the term … Meer weergeven Absorbance is defined as "the logarithm of the ratio of incident to transmitted radiant power through a sample (excluding the effects on cell walls)". Alternatively, for samples which scatter light, absorbance may be … Meer weergeven Absorbance of a material The absorbance of a material, denoted A, is given by $${\displaystyle A=\log _{10}{\frac {\Phi _{\text{e}}^{\text{i}}}{\Phi _{\text{e}}^{\text{t}}}}=-\log _{10}T,}$$ where Meer weergeven Some filters, notably welding glass, are rated by shade number (SN), which is 7/3 times the absorbance plus one: Meer weergeven • Absorptance • Tunable Diode Laser Absorption Spectroscopy (TDLAS) • Densitometry • Neutral density filter • Mathematical descriptions of opacity Meer weergeven Beer-Lambert law The roots of the term absorbance are in the Beer–Lambert law.
