FEI Tecnai G2 F20 S-TWIN HR(S)TEM

Electron Microscopy Division
FEI Tecnai G2 F20 S-TWIN HR(S)TEM

FEI Tecnai G2 F20 is a 200kV field emission gun (FEG) high resolution and analytical TEM/STEM. The field emission source means this microscope is ideal for applications requiring high coherency, high brightness at high magnification, or small focused probes. It is a versatile and flexible microscope and combines high performance in TEM, EFTEM and STEM modes with ease of operation in a multi-user research environment.
