Calculate Spectrometer Positions

This menu loads the Calculate Spectrometer Positions window which allows the user to calculate the spectrometer position for any element, x-ray and crystal combination and display the result in either JEOL or Cameca units.

 

 

There are also controls for specifying the crystal refractive index (k-value) to correct Bragg’s Law for the refractive index of the crystal material. The traditional form of Bragg’s Law is well known as:

 

 

Taking the refractive index (k) into account (from Fournelle), the expression is:
