GIF 865 Tridium ER

The chief added features of the 865 GIF Tridiem ER over the basic 863 model are as follows:

* Specially stabilized lens driver electronics on

key filter elements for minimum zero-loss jitter

* Thermally

stabilized spectrometer electronics for reduced zero-loss drift

*

Three additional octupole lenses for complete 3rd-order aberration correction

* A new decapole lens for partial correction of

4th-order aberrations to achieve even finer spectrum focus'

*

Improved isochromaticity over the entire EFTEM field-of-view (RMS energy variation reduced by a factor of 3)

* Reduced chromatic

distortion, 80% of that of the standard model: 0.25% RMS over 50 eV

*

Collection semi-angle for energy-filtered diffraction enlarged by 10%

• Field-of-view for energy-filtered TEM imaging and mapping enlarged by

10%

* Optimized BF/DF STEM detector included and integrated into

the filter entrance aperture drive assembly

* Enlarged entrance

aperture for STEM EELS work: 2.5 mm versus 2.0 mm

* Two additional

high-dispersion settings in EELS mode for high-resolution EELS work: 0.02 and 0.01 eV/pixel

The Gatan 866 is a special 865 ER (Monochromated) with even increased performance which Gatan only shipped a few times as an NSR themselves. There is no difference in software between and 863, 865, 866
