Comprehending the volume of objects through TEM |

+33 5 61 33 59 12Electron tomography makes it possible to recreate volumes at a nanoscale, by means of a Transmission Electron Microscope (TEM). Just like a medical scanner, images of a given object are made from different angles. The use of imaging software then allows the reconstruction of the sample’s volume and its 3D visualization. The preparation of samples is the same as for observation by TEM.
