A step by step operation guide
has been incorporated into the SU-1500 GUI that guides users through
the complete imaging process - from sample insertion to image acquisition.
This unique feature allows new or infrequent users to quickly obtain
excellent imaging results. This is a key factor in maintaining
the continuous workflow required in today's multi-user environments.
The SU-1500 also includes 3D animated video clips for routine maintenance
procedures. Like the operation guide, the 3D animations walk the
user step by step through the selected procedure - such as changing
the filament.
When operating various pressure
mode, the incident electron beam and the secondary electrons leaving
the sample, interact with the gas molecules in the chamber creating
positive ions. These positive ions are attracted to areas of the
sample that are negatively charged. The positive ions then combine
with the negatively charged surface of the sample to neutralize
the charging. The various pressure mode increases productivity
by allowing quick and easy imaging and EDS microanalysis of non-conductive
samples.
The wide range of available
accelerating voltage expands the imaging the analytical capabilities
of the SU-1500 by allowing the operator to choose the optimum voltage
for their particular application. A low Accelerating voltage could
be used to visualize fine features of the sample surface while
a higher accelerating voltage could be used to determine the elemental
composition of the sample. Having the choice of a wide range of
accelerating voltages can be especially important when performing
EDX microanalysis of the sample. For example, the MO-Kα line
could not be detected with an accelerating voltage of 20kV but
it could be done after the accelerating voltage was charged to
30kV.
