Absorption Coefficient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absorption Coefficient = (-1/Sample Thickness)*ln(Absorbed Power/Incident Power)
α = (-1/b)*ln(P_abs/P_i)
This formula uses 1 Functions, 4 Variables

Functions Used

ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)

Variables Used

Absorption Coefficient - (Measured in 1 per Meter) - Absorption Coefficient determines how far into a material, light of a particular wavelength can penetrate before it is absorbed.
Sample Thickness - (Measured in Meter) - Sample Thickness is defined as the total distance between the two planes of the sample taken.
Absorbed Power - (Measured in Watt) - Absorbed Power is defined as the power consumed by a solid state device while operating.
Incident Power - (Measured in Watt) - Incident Power is the intensity of the incident light ray striking the surface.

STEP 1: Convert Input(s) to Base Unit

Sample Thickness: 0.46 Micrometer --> 4.6E-07 Meter (Check conversion here)
Absorbed Power: 0.11 Watt --> 0.11 Watt No Conversion Required
Incident Power: 0.22 Watt --> 0.22 Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = (-1/b)*ln(P_abs/P_i) --> (-1/4.6E-07)*ln(0.11/0.22)

What is an Absorption Coefficient?

The absorption coefficient determines how far into a material light of a particular wavelength can penetrate before it is absorbed. In a material with a low absorption coefficient, light is only poorly absorbed, and if the material is thin enough, it will appear transparent to that wavelength. Absorption coefficient has the units [cm^-1]

How to Calculate Absorption Coefficient?

Absorption Coefficient calculator uses Absorption Coefficient = (-1/Sample Thickness)*ln(Absorbed Power/Incident Power) to calculate the Absorption Coefficient, Absorption Coefficient determines how far into a material, light of a particular wavelength can penetrate before it is absorbed. Absorption Coefficient is denoted by α symbol.

How to calculate Absorption Coefficient using this online calculator? To use this online calculator for Absorption Coefficient, enter Sample Thickness (b), Absorbed Power (P_abs) & Incident Power (P_i) and hit the calculate button. Here is how the Absorption Coefficient calculation can be explained with given input values -> 150.6842 = (-1/4.6E-07)*ln(0.11/0.22).
