Beam shift horizontal

Why do we need to shift the beam?
- To get optimal resolution, contrast and
enough light.
If you notice that a shadow sneaks into your
image, it's most probably because the beam
is not in the centered.
Use the X and Y under alignment and shift
the beam to the center. It can be useful to
minimize the beam to find the center.
Once in the center, open the beam to fill the
whole image with homogeneous light.
