Parameter
Description
Cascade Current Detector with floating amplifier electronics, for en-
hanced imaging in Variable Pressure mode up to 133 Pa. Delivers de-
tail at low kV for specimens that demand higher pressures, e.g. poly-
mers, bio specimens, pharmaceuticals, powders, and fibers. Enhanced
signal-to-noise ratio versus VPSE detector.
aBSD1-LH detector
(optional):
Pneumatically retractable 5 segment multi-mode solid state BSE de-
tector; enables materials contrast, crystal orientation, and topographic
imaging
HDBSD detector
(optional):
High definition retractable four quadrant or five segment 16 mm solid
state diode backscattered detector fitted below the objective lens as-
sembly. Provides superb compositional BSE imaging at low kV of met-
als, polymers, minerals, etc. both in HV and VP modes.
YAG BSD detector
(optional):
Robust, fully retractable, YAG-crystal-based BSE scintillator detector
with rise time ~200 ns. Easy to use with no amplifier gain adjustment
required.
HDAsB detector
(optional):
Crystallographic and channeling contrast imaging of metals and min-
erals. Four-quadrant solid state BSD diode (each segment 10 mm²) in-
tegrated in the Gemini objective lens for the detection of angular se-
lective backscattered (AsB) electrons. BSD imaging is possible at accel-
eration voltages above 1 kV. Allows operation at short working dis-
tance.
Modified instrument resolution because of the 2 mm additional
height of the HDAsB detector is indicated in the resolution values. The
WD indication is automatically corrected, i.e. the displayed WD is the
real distance between the specimen surface and the HDAsB detector
bottom side.
CL detector
(optional):
Cathodoluminiscence (CL) chamber detector (option for non-VP con-
figurations, included in VP option)
aSTEM detector
(optional):
Pneumatically retractable multi-mode annular Scanning Transmission
Electron Microscopy (aSTEM) detector, with 12x specimen holder; en-
ables bright field (BF), dark field (DF), oriented dark field (ODF), and
high angle annular dark field (HAADF) transmission imaging
Chamber camera
Color CCD camera
with white-light illumination and IR illumination.
Specimen current
monitor
Auto ranging for precise current measurement in the range of 1 pA to
10 μA
