Aperture assembly
The aperture assembly is used, after the beam is centered, to verify the axial alignment between optical and mechanical
alignments.
1. Insert the aperture assembly into the upper lens bay.
Orient the tab straight out the front of the lens bay, with
the counterbore toward the left and rear (see figure
below). The diameter of the aperture assembly
prevents the lens bay door from closing all the way.
2. Remove the nozzle and place a beam card or tape over
the nozzle adapter opening. Pulse the beam to cause an
imprint but do not ignite the material. Check that the
imprint and the nozzle adapter opening are concentric.
If not, the beam axis and mechanical axis are incorrectly
aligned and need to be adjusted.
3. Make necessary adjustments and repeat the procedure
until the beam pattern is centered with the crosshair
and the aperture imprint is concentric with the nozzle
adapter’s opening.
