Adjusting the Ar laser position
Figure 5.4-42
In the LU4A four-laser module A, the coupled laser
light does not pass through the AOTF before the
laser coupling mirror part. The AOTF is located
beyond the laser coupling mirror part where the four
laser lights are coupled.
1. Select the line three (L3) with the AOTF remote
controller to use the 488-nm Ar laser.
2. Unscrew the two hexagonal bolts at the laser
coupling mirror part and detach the laser coupling
mirror part.
Precautions
At the detachment of the laser coupling mirror
part, the collimation pin may come with the laser
coupling mirror part. Be careful to prevent the
pin from getting lost.
