beam alignment
It is possible that due to transportation, rigging, moving
around or vibrations caused by various elements during
a set up or laser performance some of the internal optical
parts can move slightly resulting in colour misalignment.
The colour misalignment is when two or more colours
(red, green and blue) physically do not overlay each other
properly like on the picture below. This makes it impossible
to get nicely mixed colours like yellow, cyan, magenta and
white (including all their shades). If this occurs it is necessary
to carry out the beam alignment procedure.
Beam alignment principle
There are three laser modules within this system where
each module produces one of the basic RGB colours (red,
green or blue).
The goal of the alignment procedure is to align all three
beams (colours) so they overlay each other nicely while
they hit exact centre of the bottom scanning mirror.
An easiest way to do the alignment is to project a full
size circle onto a wall (or any another suitable projection
surface), change its colour as necessary and check the
alignment of individual colours on both X and Y axes.
i
Remember that greater is the distance
between the laser system and the
projection surface during the alignment,
more precise the alignment will be.
When doing the alignment on long distances it is always
good to have someone with you who can point you in the
right direction. Alternatively you can use binoculars.
!
Be cautious when aligning the beams and
wear sufficient laser safety protection
to avoid accidental exposure to Class
4 laser radiation.

Please note that if you opted for
Motorised Dichroic Filters when
purchasing this laser display system, the
beam (colour) alignment is done directly
from FB4 interface or via special utility
in projector settings in Pangolin Beyond.
If your laser system is equipped with
Motorised Dichroic Filters, do not follow
the instructions on the following pages
and check “HOW TO: align colours with
Motorised Dichroic Filters” quick manual.
