for live image scanning and corresponding image resolution. This section outlines

few general tips for good SEM photos.

• The Scanning Mode is adjusted via the green toolbar buttons. Scan3 and Scan4 are the
only modes recommended for photography. Images taken on the Scan4 mode are less grainy
than those acquired in Scan3 mode.
• The Scan Speed is adjusted in the Scan…Scan Speed section of the Setup…Fundamental
Setup pull down menu. The default scan time settings are 10s (640x480) for Scan3 and 80s
(1280x960) for Scan4.
• Image Format is selected in the pull down box after the image is frozen and the Save button
is pressed.
• Image Size is a function of both scan speed and image format. JPG images are relatively
small, and TIF images are relatively large. JPG images generally work fine for most users.
Lower Resolution (but quick) Photos
1. Press the green Scan2 button on the toolbar.
2. Adjust the focus, contrast, and brightness (or use the automatic features). It is good practice
to focus the image at a higher magnification, then back down to the desired photo
magnification.
3. Freeze the image by pressing the green Scan3 toolbar button followed by the green Freeze
toolbar button.
