Preparations
Remove the screws of the front lid. Lift the lid and unplug the earth connector on the left
power supply section of the AttaXX. Be sure to work in a dust-free ambient, so the optical
section is not contaminated. Now safely store the top cover and avoid touching the output
window. During aligning process, also make sure not to touch any optical surface with sour
fingers. Inside the AttaXX, high quality optical components are used, and not all optical
surfaces can be cleaned the usual way. Most of the mirrors are very high reflective protected
silver mirrors, cleaning is not recommended. If, in any case, the surface is dirty, it is
recommended to replace the mirror.
Apply an input signal to the DB25 ILDA connector on the back of the AttaXX. You can
either do this with an external power supply or a standard laser software by projecting a white
dot or small circle.
All AttaXX RGB models:
Basically there are three
laser devices for red, green
and blue color. Depending
on output power and setup
of the AttaXX projector,
different laser modules are
used, which are coupled and
aligned to one single beam.
But in any case, each single
color is mixed to one beam,
before it enters the main
optical mixing section. The
AttaXX Plus models mostly
contain 4 laser devices.
Procedure is quite easy, but should only be done by an experienced service technician. All
color lines must be parallel from the last dichroic filter on the red laser to a distance of
minimum 10m projection size.
The green laser beam is your reference of the optical mixing system. Adjust the green beam
with the mirror mount. Make sure, the beam is parallel to the base, and hits the galvo mirror
properly.
Now adjust the blue laser line in the same procedure. Align both beams properly on top of
each other, parallel onto the galvo mirror mount, and, at the same time, parallel in far
distance.
Use the same procedure on the red laser.
Finally, all single beams and colors should match on the galvo mirrors and also after a
distance of 10-20m. Once the system is aligned, it should not misalign again. During
alignment procedure, please check all mirror mounts for proper function and cleanness.
