Tecnai F20

Mission:

The Tecnai F20 microscope is a field emission 200 kV scanning transmission electron microscope (TEM) with a super TWIN objective lens and high brightness field emission electron gun optimized for analytical work.

Features:

  • Objective lens allows a +/-35 degree tilt with a standard low-background double tilt holder and, with the tomography holder, allows +/-65 degrees of tilt. 
  • Equipped with energy dispersive analysis of X-rays and a silicon drift detector with resolution of 129 eV or better.
  • Super ultra-thin window and windowless versions provide superior light element performance. 
  • Uniquely designed 30 mm2 silicon drift energy dispersive X- ray detector chip optimized for solid angle.
  • Direct detection device camera provides up to 160 fps tempol resolution for in-situ TEM.
  • Gas supply system available for in-situ environmental TEM operation.
  • Various techniques are integrated into the instrument software for ease of operation.
