6. Justage
If the single diodes in the array module aren‘t perfectly aligned anymore it is necessary to
realign them.
1. Reduce the power of the module to 30% or connect the module with a modulation
voltage between 2-3V (the adjustments can only be done with a static single beam).
2. The optimal alignment distance for this modules is between 15 and 20 met-
res. To have a better viwe on the laser beam while standing next to the projec-
tor, use a beam mirror to reflect the laser beam back to the projector. The re-
flected laser beam needs a vertical projection surface . If there are more than
one laser point visible on the surface ,alignment of the mocule is necessary.

4. Use a 2mm Allen Key and turn one of the screws of diode 2 and check what happens.If the
beam profile becomes worse and you can see that this diode was properly aligned, just
undo the step by turning the screw back. If the diode you now moved seems to be out of
alignment, use the four screws to property align it to the diode 1.
During the adjustment please take care of:
•
The movement trace of the beam during the alignment is diagonal; if you want to
move the beam higher, you have to tighten both top screws a little bit.
•
TAll screws have a tightening torque of 20-30cNm
•
If a screws has reached the maximum torque and the position of the beam is still not

correct, you have to loosen the screw a little bit. After this step you can tie the other
screw again.
5. Follow the step 4 to calibrate all disaligned diodes. Always start from the first diode in the
row and proceed diode per diode. Never touch the very first diode, it is the master beam.

Inputs related to GND (0.0 - 5.0 Vdc; OV --> off; 5V --> 100%) for Red + Blue are pins 9 + 11. The
shutter is the enable input and have to be used.
