DTU Nanolabs Tecnai T20 is a transmission electron microscope (TEM) used for performing both conventional imaging and diffraction, high resolution and scanning transmission microscopy (STEM) measurements. It is a versatile instrument, ideal for studying a wide range of general and advanced materials, soft matter, composites, etc. The microscope is equipped to carry out chemical analysis as well as Cryo-TEM for soft materials.

The Tecnai T20 is a transmission electron microscope equipped with a thermionic electron source with a Lab6 filament and acceleration voltages that can vary between 80-200 kV. It has the FEI super-twin (S-Twin) pole piece with a pole piece gap of 5.2 mm (Cs about 1.35 mm). This gives the microscope a resolution @ 200 kV of 1.4 Å in TEM mode. Other tecniques available on the microscope are scanning transmission electron microscopy (STEM, resolution 10 Å) with a high-angle annular dark-field detector (HAADF). Additionally, it is equipped with retractable cryo plates, which makes it ideal for cryo experiments.

On the analytical side, the microscope is equipped with an Oxford X-Max 80T SDD X-ray detector for Energy Dispersive X-ray (EDS) spectroscopy and a Gatan Tridiem 863 imaging filter allowing for electron energy-loss spectroscopy (EELS) and energy-filtered imaging (EF-TEM). For imaging, the microscope is equipped with TVIPS XF416 CMOS (4096×4096 px) before the the energy filter and a GATAN Ultrascan US1000 (2048×2048 px) after the energy filter.
