Diffraction Imaging and SPED

MerlinEM detectors offer unique opportunities for electron diffraction imaging. The simultaneous high dynamic range, high frame rate and ability to count single electrons massively expand the usefulness of this very established set of techniques. On top of this, the MerlinEM is radiation safe even at 300kV so there is no need to use a beam stopper.

Modern fast framing electron detectors like MerlinEM allow practical imaging of a full distribution of electrons for each probe position in a scanning transmission electron microscope (STEM). The most common name of the technique is 4D STEM, however, scanned diffraction or momentum resolved STEM are also used.

Cryo-EM Single Particle Analysis

Single particle analysis is a group of related computerized image processing techniques used to analyze images from transmission electron microscopy (TEM).

Ptychography is a subset of Coherent Diffractive Imaging (CDI) which uses a coherent energy source (in our case, electrons or X-rays) to illuminate a sample and retrieve the phase information on the sample from phase-retrieval analysis of the far-field diffraction pattern.
