# Sample Transmission Calculator¶

## Overview¶

The sample transmission calculator allows the calculation of the sample transmission and scattering over a given wavelength range for a particular sample material and geometry.

This UI is a front end for the CalculateSampleTransmission algorithm.

The algorithm assumes a flat plate sample which is perpendicular to the beam.

### Input Wavelength¶

The wavelength range to calculate transmission over can be given either by providing a single binning range in the format of a start, width and end value or by providing a bin parameter string as used in the Rebin algorithm.

### Sample Details¶

The sample details required are the chemical formula which is to be given in the format expected by the SetSampleMaterial algorithm, number density per atom in $$atoms/\mathrm{\AA{}}^3$$ and thickness in $$cm$$.

### Output¶

The output is given in a plot of the transmission percentage over wavelength and a table of statistics for the transmission (maximum, minimum, mean, median and standard deviation) as well as the scattering percentage for all wavelengths.
