1.
Place the thin, flat, sample onto a window (or across an aperture) and use the joystick
to bring the sample into visible focus.
If necessary, use the
Auto-Focus
option to focus the image.
2.
Set the apertures to the appropriate size for the sample area, and mark this position
using the
Add Marker
option from the
Microscope
menu.
3.
Use the joystick to move the sample away from the center of the viewing screen, and
focus on the top surface of the window.
Use the
Monitor
function (from the Measurement toolbar) to monitor the energy
throughput. Either manually adjust the lower cassegrain for maximum energy using the
up
or down
buttons of the
Correction
function, or use the
Maximize Energy
facility.
4.
Once the maximum energy through the window (or aperture) has been achieved, click
Halt
on the Measurement toolbar.
5.
Run a background spectrum through this point on the window (or aperture) using the
correct aperture size as selected previously.
6.
From the
Stage Move
menu in the
Microscope
menu, select
To Selected Marker
and
record the sample spectrum.
This procedure for correction of window materials should be done for single point, mapping
and imaging experiments.
If the same window is used repeatedly for analysis, this height correction of the lower
cassegrain need only be done once.
