(4) Test the alignment of the first and second mirrors when distant
When the first and second mirrors are well-aligned in Position A, slowly and gently move the
X-axis beam to Position B (Figure 4 – 4) far away from the laser tube. Push the Test Switch
button to activate the laser and produce a second spot on the tape on the second mirror.
(5) Test the alignment of the second and third mirrors when close
Put the double-sided adhesive tape on the third mirror (3#). Move it slowly and gently along
the Y-axis guide rail until it is in Position 1 (Fig. 4 – 5) near the second mirror. Push the Test
Switch button to get a laser spot on the tape. To avoid being burnt by the laser, please put a
carton board in front of the third mirror to get the general position of the laser spot.
