Electron wavelength as a function of accelerating voltage
Add unrelativistc equation too!
Source: Williams & Carter TEM textbook
Note: Chromatic aberration and effects of source size not factored in.
Probe Size (diameter) based on semi convergence angle
Add in Chromatic abberration!!!
Add in r_min
Add in B_optimum
Add in Depth of Focus (elbaum?)
