This produces the smallest tails but increases the FWHM (minimum rms radius approx. 43(Cs λ 3 )1/4 ) to about twice that of the probe with Scherzer conditions. Scherzer conditions seem to be a compromise between a small full width half maximum and large tails. Mory et al. [254] have 54 3 Linear Image Approximations also considered the optimum probe defocus for STEM imaging and microanalysis. Intaraprasonk et al. [171] have discussed optimizing the probe with spherical aberration through fifth order.

A focused probe is calculated by integrating the aberration wave function exp[−iχ (k)] over the objective aperture with translation to a particular point in the image. 9 shows the relative placement of the wave functions in the STEM column. 59) where λ kmax = αmax is the maximum angle in the objective aperture and A p is a normalization constant chosen to yield; |ψ p (x, x p )|2 d2 x = 1. 60) With this normalization the total incident intensity in the electron probe is also unity (alternately the probe integral could be scaled to yield the actual value of the beam current in some appropriate choice of units).
