  200 kV Transmission electron microscopes 
These are the microscopes used in materials research and for the most advanced biological applications. The high accelerating voltage improves the resolution to enable resolution of individual rows of atoms, increases the penetration of thick or dense samples and increases the electron intensity in the focused beam used for analysis or  Z-contrast STEM imaging.

Apart from giving superb images at a wide range of magnifications and having powerful facilities for electron diffraction studies, these TEMs are often equipped with analytical spectrometers for X-ray analysis and in-column or post-column electron energy spectroscopy and energy filtered imaging.

The material research models of the 2200/2100/2010 series can produce an intense focused beam of less than 0.5 nm size. This capability  combined with the high electron intensity achieved with a field emission gun results in a powerful system for sub-nanometer analysis and ultrahigh resolution HAADF STEM images.

All these microscopes can be equipped with a range of polepieces permitting the user to choose an optimum configuration depending on applications.

The specifications on resolution and magnification given below are all based on the high resolution versions.
