The usual intent of laser manufactures is to produce a laser diode driver with as linear response behaviour
as possible. So when the diode current increases, the optical power and light intensity grow linearly.
The problem is that human eye senses brightness of light logarithmically over a moderate range (Weber–
Fechner law). So when light intensity grows linearly, human eye and brain don’t see it that way and our
visual perception of colours changes.
In the world of laser display systems this generates problems when we work with mixed colours (i.e.
yellow, magenta etc.). Normally the mixed colours coming out of laser systems do not entirely correspond
with those we see on computer screens – because of the dierence in visual perception.
In order to synchronise all the colours we see on our screen and those coming out of the laser device
we do, so called, palette calibration procedure in the laser control software. This can be of course rather
lengthy process and even if it’s done properly, the calibrated palette will always be tied to particular
control system or profile that was used during the colour calibration and not to the laser projector itself.
So we came with the idea to hard-code the “calibrated palette” into every Clubmax FB4 laser system in
our factory during the manufacture. No matter what control interface you use or what control signal is
used (Ethernet, DMX, ILDA), the calibrated palette is always there, ready for you to be switched on by
Colour Balance button.

9. ILDA INPUT/OUTPUT. ILDA INPUT connector is used for the control signal input from an external control interface.
ILDA OUTPUT connector is used to daisy chain the control signal between multiple laser systems.
10. Safety eyelet. Use this together with appropriate safety wire to secure the system against unexpected fall.
