Tips for steering the beam path

Procedure 6 Obtaining the optimum beam pattern and/or power
1. With the beam output being monitored, turn either the I or II output mirror
thumbscrews an eighth to a half turn to improve the beam pattern or power.
2. Using the matching pair thumbscrew on the input mirror, counter the change
from the output mirror screw as follows:
•
For pair I, turn the input mirror thumbscrew the same direction that the
output mirror thumbscrew was turned.
•
For pair II, turn the input mirror thumbscrews the opposite direction that
the output mirror thumbscrew was turned.
3. Repeat and note the peaks and values in the beam pattern quality and/or
power as you move the beam across the mirrors.
4. From your observations, set the thumbscrews of the axis to the best pattern
quality and/or power
5. Repeat steps 1 to 4, using the thumbscrews of the other axis.
Note: As you move from coarse alignment to fine alignment, the sensitivity of the
thumbscrews increases. Therefore when performing a fine alignment with a pow-
er meter only, turn the thumbscrews in smaller increments.
Pinhole sliding
When performing the coarse alignment procedure with the pinhole positioned
near to the CONNECT output mirror, you can additionally loosen and manually
slide the alignment tool further away from the mirror. Moving the pinhole further
