GIF Tridiem:
The New Gatan Imaging Filter

The New GIF Tridiem represents Gatan's 3rd generation of post-column energy filters. Incorporating 3rd-order aberration correction and Gatan's state-of-the-art UltraScan™ 2K x 2K sensor, the new GIF Tridiem efficiently gathers the most complete and revealing EFTEM and EELS data sets ever.

The GIF Tridiem, combined with the Gatan Microscopy Suite (GMS) software, is ideally suited for generating and working with the rich 3-dimensional data sets demanded by today's analytical electron microscopists, including EFTEM and EELS STEM spectrum images, EFTEM tilt and tomography series, and time series. GIF Tridiem makes such tri-dimensional EM readily accessible.

The Gatan Imaging Filter comes with sophisticated software covering all aspects of energy-filtered imaging and energy-loss spectroscopy. A graphical user interface within DigitalMicrograph simplifies the acquisition and processing of filtered and unfiltered images, and powerful EELS software allows complex analysis of energy-loss spectra. Tight integration of the software with the microscope and simple expandability through additional Gatan plug-ins make it a safe investment for the future.

Key Features of the GIF Tridiem include:

• Large collection semi-angle for energy-filtered diffraction: 120 mRad, full azimuth (on selected TEM models)

• Large field-of-view for energy-filtered TEM imaging and mapping: 20 µm, diagonal (on selected TEM models)

• Excellent isochromaticity over the entire EFTEM field-of-view: deviations < 1.25 eV

• Very large searchable field-of-view in unfiltered TEM mode: > 200 µm, diagonal (on selected TEM models)

• Rich EELS detail with each spectrum readout: > 2000 channels (e.g. capture 600 eV range at 0.3 eV/channel)

• Exclusive "cinema mode" readout for smooth, high-quality real-time viewing: > 10 frames/sec

• High spectrum readout rate for STEM spectrum imaging: > 30 spectra/sec
