The Gatan Image Filter (GIF) is mounted below the TEM camera chamber and it allows the capability of energy-filtered imaging, compositional mapping and and TEM image contrast enhancement by filtering (removing) of inelastically scattered electrons.
The GIF Quantum is Gatan's most advanced post-column energy filter. It combines new electron optics with a fast CCD camera which enables the fast capturing of highly detailed electron energy loss spectroscopy (EELS) and energy-filtered TEM (EFTEM) data. With the GIF Quantum it is also possible to do 3D electron tomography in EFTEM mode. Gatan software also provides the option for 3D tomography in TEM and STEM mode. This application will therefore, apart from the GIF Quantum hardware and software, also include the Gatan 3D tomography software (acquisition, reconstruction and visualization), computer for image reconstruction and Gatan ultrahigh tilt tomography specimen holder which provide the complete solution for 3D electron tomography in TEM, STEM and EFTEM mode.
