Centering the x-y Stage
The x-y stage should be centered with respect to the center of rotation before
beam alignment is performed. This can be accomplished using the stage
alignment tool, which is a small clear plastic piece, with a small hole in the
center and two larger holes near the outside.
1.
Insert the alignment screen.
2.
Install the Stage alignment tool. Align the two outside holes to the
adjustment positions of the x-y stage.
3.
Turn on bottom illumination.
4.
Using the multipurpose tool, or a 1.5 mm hex wrench, adjust the
position of the x-y stage until the hole in the alignment screen is
aligned to the hole in the stage alignment tool.
Be careful that your eye
is directly above the hole in the stage alignment tool during adjustment.
The 5x loupe can be used to aid this alignment, however, it is very
important that it is aligned exactly between your eye and the hole.

To Verify the Alignment:
1.
Lower the sample and start the rotation.
