GIF 2002
The GIF 2002 is a TEM energy filter optimized for high-resolution EFTEM imaging. Its 2K x 2K sensor features high sensitivity and large pixel size for optimum detection quantum efficiency (DQE) for low-contrast specimens that must be imaged at low dose. The GIF 2002 is thus well suited to applications in structural biology and for imaging of other beam-sensitive samples.
As with the GIF 2001 model, a retractable TV-rate camera is provided for real time instrument adjustment and experiment setup. The GIF 2002 also features the industry-leading, self-tuning, aberration-corrected filter optics for which all Gatan energy filter systems are known.
Although not optimized for EELS work, the GIF 2002
can also produce high-quality EELS spectra. However,
the large size of the sensor limits the readout speed
that can be achieved in this mode to about 2 spectra
per second. Furthermore, only the central 1024-pixel
range of the detector can be used for EELS readouts.
This GIF model is therefore not recommended for STEM
EELS and spectrum imaging applications. For such applications,
please refer to model 863 GIF Tridiem.
Key Features of the GIF 2002 Hardware include:
Advanced electron optics using multipole lenses
2K x 2K pixel MultiScan™ CCD camera with 30 micron pixel size
Second order aberration corrected energy dispersive prism
Third order image aberation correction
Compatible up to 400 keV and with HV TEMs
Fully digital computer contolled PC based system
Complete system specification sheet available upon request (Gatan document 001.01010)

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 2002 Software include:
