102 Thorlabs Beam 4.0
Note
When mounting the mirrors ensure to keep some space between the second mirror
and the translation stage. Mind that you might like to add a lens and/or an iris
diaphragm.
Doing The Beam Alignment
If the laser beam is already led over the two mirrors to the beam profiler a convinient
way to align the laser beam is described in the following.
Assuming that the stage position at the beginning of the drive is position P1 (0 mm)
and the position at the end is P2 (150 or 300 mm). And assume that the two mirrors
in front of the translation stage are M1 and M2 (see picture above).
First the stage has to be positioned at P1, then the knobs of the mirror M1 have to
be turned for positioning the laser beam in the middle on the camera sensor. If this is
done drive the stage to position P2. Here the knobs of mirror M2 have to be set up
till the beam is centered again. Repeat these steps as long as the beam moves
clearly when the stage moves from P1 to P2.
It is important to turn only one mirror for the corresponding stage position. Then this
method will lead to a laser beam parallel to the translation stage axes. The beam
should be in the middle of the sensor for any stage position.
