== Description ==
The Tecnai TF-30 is a transmission electron microscope (TEM) that can also be operated in scanning transmission electron microscopy (STEM) mode, with a voltage range of 80 to 300 kV. Operation at 300 kV makes this the KNI's highest resolution TEM (see also the 200 kV [[Tecnai_TF-20:_200_kV_TEM,_STEM,_EDS,_EELS,_EFTEM_%26_Lithography | Tecnai TF-20]]). The TF-30 is also equipped with a high-angle annular dark field (HAADF) detector for use in STEM mode, and an energy dispersive spectroscopy (EDS) detector for compositional analysis (in both TEM mode and, most usually, in STEM mode). The Serial EM program allows for automated collection of images at variable tilt angles for performing tomography. See a full list of training and educational resources for this instrument below.

Description

A schematic of the KNI's Tecnai TF-30 TEM/STEM. Modified from an original schematic that is courtesy of Portland State University.

The Tecnai TF-30 is a transmission electron microscope (TEM) that can also be operated in scanning transmission electron microscopy (STEM) mode, with a voltage range of 50 to 300 kV. Operating at 300 kV, the TF-30 has analytical options such as EELS and EFTEM. The TF-30 is also equipped with a high-angle annular dark field (HAADF) detector for use in STEM mode, and an energy dispersive spectroscopy (EDS) detector for compositional analysis (in both TEM mode and, most often, in STEM mode). The Serial EM program allows for automated collection of images at variable tilt angles for performing tomography. See a full list of training and educational resources for this instrument below.

Applications
  • High-Resolution TEM (HRTEM) imaging without an objective aperture
  • Bright Field (BF) & Dark Field (DF) imaging with an objective aperture
  • Selected Area Electron Diffraction (SAED)
  • STEM imaging with a High-Angle Annular Dark Field (HAADF) detector
  • Energy Dispersive Spectroscopy (EDS) with an Oxford INCA system
  • Automatically capture tilt series of images for tomographic imaging
