Adjusting the Focus on the 1721/1722
The recommended working distance range is 1 to 80.0mm for the wafer reader in the
vertical position. If using the horizontal mirror mount, the recommended working distance
range is 1 to 56.0mm.
Once the working distance is established and an image is acquired, the focus can be
adjusted using the focus adjustment screw (M3 hex screw), located in the center of the
wafer reader’s front face-plate (see Figure D-4). To adjust the focus, use a 2.5mm Allen
wrench. Turn the focus adjustment screw clock-wise if the wafer reader is moved closer
to the wafer; turn the screw counter clock-wise if the wafer reader is moved farther away
from the wafer.
