TESTS & ALIGNMENTS
Step 3: Verify No Clipping at
Beam Combiner and at Mirror #1.
1. Open the lid.
2. Place Thermal Paper: Take a small
piece of thermal paper (approximately
1 inch (25 mm) should be plenty) and
place it firmly over the beam combiner
near the aperture side of the laser, see
figure 36.
3. Press the paper down with your finger
so that a circle appears that
demonstrates the outer rim of the
lens. Sometimes pencil lead or crayon
will help to show the edges of the lens
and mirrors.
4. Close the lid.
5. Using the touch screen display, test
fire the laser from the Test Fire screen.
The Fire button will appear after all of
the system checks have passed. Press
the button one time and observe
where the spot lands on the thermal
paper. (From here forward called *Test
Fire*)
6. The spot should be centered on the
beam combiner. Remove the thermal
paper.
7. Repeat steps 2 – 5 at Mirror #1 (Fig.
37).
8. The spot should be nearly perfectly
centered at Mirror #1 and not clipped
by the beam combiner. If it is not,
there is a problem with the tube
mounting as there is very little to
adjust between the tube and the
mounting of Mirror #1.
9. Remove the thermal paper and clean
all tape residue from the beam
combiner and Mirror #1.
Spot should
be centered.
Clipped spot
indicates an
alignment issue.
