Low Voltage Transmission Electron Microscope

CORDOUAN Technologies, specialized in nanomaterials caracterisation by dynamic light scaterring (DLS) technology joins the Delong Group to introduce in France the rst benchtop transmission electron microscope that combines TEM, SEM and STEM imaging. CORDOUAN Technologies initiates an exclusive partnership with the Delong Group to promote a unique imaging tool : the benchtop transmission electron microscope LVEM 5. Compact & powerful Electron microscopes are indispensable tools for the investigation of objects at the micro and nano scale. The LVEM 5 can help you get the information you need....

Components Field emission gun (FEG) and advanced electron optics The electron gun uses a Schottky eld emitter which provides high brightness and coherence with a lifetime of several thousand hours. The high brightness and small virtual source of the electron gun allows transmission and scanning modes. Permanent magnet lenses, an electrostatic lens and electrostatic stigmators and deectors are used in the electron optics. Permanent magnet lenses are very stable and do not need any cooling. Two-stage magnication The design of the LVEM 5 diers considerably from that of standard TEM. The...

Wide choice of imaging modes The LVEM 5 is the smallest commercial transmission electron microscope in the world. It features all the standard imaging modes that can be found in conventional TEMs and more. The LVEM 5 can work in transmission (TEM – Transmission Electron Microscope) or diraction (SAED – Selected Area Electron Diraction) modes as well as in scanning modes (STEM – Scanning Transmission Electron Microscope and SEM – Scanning Electron Microscope with BSE – Backscattered Electrons) with nanometer spatial resolution. TEM (with SAED) TEM (with SAED) + STEM TEM (with SAED) + SEM TEM...
