Step 3: Laser Installation
•
Place the alignment plate into the cage system
right before the 45° mirror, see image to the right.
•
Insert the laser into the mount without securing it
with the locking screws yet.
•
Turn the laser on and observe the pattern on the
alignment target. You will see an elliptical shape.
•
Rotate the collimator in the housing until the long
side of the ellipse is oriented in vertical direction.
•
Fix the locking screws. Make sure the locking
screws fix the collimator close to the thread, see
image below.
Step 4: Laser Mount Alignment
•
Turn the tip and tilt screws on the KC1-T mount until
the brightest spot of the laser light distribution hits
the hole in the alignment plate.
•
Turn off the laser.
•
Remove the alignment plate.
Step 5: Adjustment Mirror Alignment, Part 1
•
The second (upper) adjustment mirror must also be
removed from its mount. To do this unscrew the set
screw, place a piece of adhesive tape on the back of
the mirror and pull it out of the mount.
•
Insert the ADF1 disk into the KCB1C(/M), ideally with
the reticle aligned to the axis of the mount.
•
Turn on the laser.
•
Adjust the lower adjustment mirror so the laser beam
exits the upper KCB1C
vertically
. For that, make
sure the laser spot is centered on the reticle.
•
Turn off the laser.
•
Remove the reticle and place the mirror back into the
mount and fix the locking screw.
