6.4.6. Generating an image
Procedure
1 Select the Apertures tab.
2 From the drop-down list, select the aperture size 30 µm.
3 Select the Detectors tab.
4 From the Detectors drop-down list, select Sig-
nal A = SE2.
We recommend using the SE2 detector to ob-
tain the first image. This detector provides a
good signal-to-noise ratio even at long working
distances.
5 Select the Scanning tab.
6 From the drop-down list, select
Scan Speed = 1.
The lower the scan speed number, the faster
the electron beam scans across the specimen.
Scan Speed = 1 allows you to get an image
quickly.
