A cold field emission transmission electron microscope fitted with spherical aberration corrector (Cs) on the probe-forming lens systems. The HF5000 is capable of imaging atomic structures with a resolution of less than 80 pm. It can acquire atomic chemical information using energy dispersive X-ray spectrometry (chemical information) and electron energy-loss spectroscopy (chemical and bonding information). The microscope provides electron tomography for three-dimensional imaging of structures. In addition, several side-entry in situ specimen holder systems are available for a variety of in situ experimental work.
