set later if additional adjustment is desired. This is done by re-clicking the Set
Target Position button.
In Step 6, you acquire the Motion Matrix. Click the “Acquire Motion Matrix”
button. Over the next several minutes, the system will move each motor (X1, Y1,
X2, Y2) by pre-defined amounts in the positive and negative directions and stop
once it has gathered enough information or the beam has moved to the edge of the
optical aperture. Once the Motion Matrix has been acquired, the green light next
to the Acquire Motion Matrix button will be lit.
In Step 7, you acquire the target size. Click the “Acquire Target Size” button and
the software will analyze the noise of the beam to determine a recommended
target size for the motion settings. (The recommended target size can be changed
later if desired.) Click the Finished button to close the System Set-up window and
save the settings via the subsequent pop-up window.
