Beam alignment principle
There are three basic RGB colours (red, green and blue) produced by a laser module (except one colour models such as
LogoLas G10 and no need for beam alignment).
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.
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.
Remember that greater is the distance between the laser system and the projection surface during
the alignment, more precise the alignment will be.

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.
Be cautious when aligning the beams and wear sufficient laser safety protection to avoid accidental
exposure to Class 4 laser radiation.
