The term absorption refers 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. Zobraziť viac 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 defined … Zobraziť viac Attenuance Absorbance is a number that measures the attenuation of the transmitted radiant power in a material. Attenuation can be caused by the … Zobraziť viac Logarithmic vs. directly proportional measurements The amount of light transmitted through a material diminishes exponentially as it travels through … Zobraziť viac Beer-Lambert law The roots of the term absorbance are in the Beer–Lambert law. As light moves through a … Zobraziť viac 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 Zobraziť viac Some filters, notably welding glass, are rated by shade number (SN), which is 7/3 times the absorbance plus one: Zobraziť viac • Absorptance • Tunable Diode Laser Absorption Spectroscopy (TDLAS) • Densitometry Zobraziť viac WebFor example, an absorbance of 3 means that the optical power is attenuated by the factor 10 3 = 1000. That would correspond to an attenuation by 30 decibels and a transmittance of …
