ALIGNMENT PROCEDURE FOR CO
2
WAVELENGTHS (9.3 UM AND 10.6 UM)
1. Bolt the laser alignment fixture to the front face of the AGV3D.
l
Use the 6x12 mm LG dowel pins and M6x1.0 70 mm LG socket head cap screws provided
with the alignment fixture.
l
The large cut out should point up.
2. Tape fax paper (or other heat-sensitive paper) to the front alignment target. Poke a pinhole in the
paper that is aligned with the pinhole in the front alignment target.
3. Fire one or two pulses of the laser and then inspect the mark on the fax paper to see if the mark is
concentric with the pinhole. Use a ruler to measure the mark for large beams.
4. If the mark is concentric with the pinhole, proceed to Step 5. If not, adjust the position of the laser
and repeat Steps 2 and 3 with a new piece of heat-sensitive paper. Use a new sheet of paper for
each test until the laser beam is correctly centered on the target.
5. Remove the front target from the alignment fixture.
6. Determine if the beam is aligned with the pinhole on the rear target. Follow the procedure in
Steps 2 and 3 with the rear target.
7. If the beam is not centered on the rear target, adjust the angular position of the laser source until
the beam is aligned with the rear pinhole. Follow the same procedure in Steps 2 and 3 to check
the beam position.
8. If angular adjustments were required in Step 7: Replace the front target in the alignment fixture
and verify if the beam is still centered on the front target. Make positional adjustments to the
laser source to recenter the beam.
9. Repeat Steps 2 through 8 until the beam is aligned with the rear target pinhole and the front tar-
get pinhole.
10. Remove the laser beam alignment fixture, M6 SHCS, and 6 mm dowels from the front face of the
AGV3D.
