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
