The novel ultra-low voltage SEM Delta [1,2] allows electron spectroscopic imaging of both secondary (SE) and backscattered (BSE) electrons with a primary energy down to 50eV and a resolution better than 1nm. To recover the true sample spectra, we use Bayesian inference, a tool applying forward simulations. This statistical approach is especially suited to deal with the stochastic nature of the measurement process and provides physically motivated error estimates.
