Normalized Intensity Calculator

Formula

The formula to calculate the Normalized Intensity (I_n) is:

$I_n = \frac{I_s - I_b}{I_r - I_b}$

Where:

$I_n$ is the normalized intensity
$I_s$ is the intensity of the sample
$I_b$ is the intensity of the background
$I_r$ is the intensity of the reference

What is Normalized Intensity?

Normalized intensity is a measure used to compare the intensity of a sample relative to a reference, taking into account the background intensity. This normalization process helps to remove the effects of background noise and allows for a more accurate comparison of sample intensities. Normalized intensity is commonly used in scientific experiments and data analysis to ensure that the results are not skewed by external factors.

Example Calculation

Let's assume the following values:

Intensity of the Sample (I_s) = 150
Intensity of the Background (I_b) = 50
Intensity of the Reference (I_r) = 200

Using the formula to calculate the Normalized Intensity (I_n):

$I_n = \frac{I_s - I_b}{I_r - I_b} = \frac{150 - 50}{200 - 50} = \frac{100}{150} = 0.6667$

The Normalized Intensity (I_n) is 0.6667.
