This instrument is an advanced and digitally dedicated transmission electron microscope operating at 200kV with a field-emission gun. It is capable of an ultimate point-to-point resolution of 0.19 nm, with the ability to image lattice fringes at 0.14 nm resolution. It is a multipupose ultrahigh resolution analytical electron microscope with a wide range of capabilities such as high-resolution image observation, nanoarea X-ray analysis, versatile analysis by convergent-beam electron diffraction, and analysis of the atomic structure and/or bonding state of atoms. With the addition of Energy dispersive X-ray spectrometer (EDS) and Parellel electron energy loss spectrometer (PEELS), the field-emission TEM can also be used as an elemental analysis tool, capable of identifying the elements in areas less than 2 nm in diameter.
