General Information
The following chapters explain important information about lasers in general, basic laser
safety and some tips about how to use this device correctly.
Please spend some time reading these information as some of them are critical for safe
and efficient operation of this laser display system.

Caution
Please note that some other optical devices such as cameras, camcorders, video projector etc. can be
damaged if exposed to excessive laser radiation.
Handling precautions
This laser system is a precision device that contains some sensitive opto-electronics components. DO
NOT drop it or subject it to physical shock.
Do not leave the laser system in excessive heat such as in a car whilst in direct sunlight. High
temperatures could cause some serious damage to the system.
The laser system contains precision electronic circuitry. Never attempt to disassemble the laser yourself.
If the laser is suddenly brought in from the cold into a warm room, condensation may form on the laser
and internal parts. If condensation forms on the laser body, do not use the laser as this may damage the
laser system. If there is condensation, wait until it has evaporated before using it.
This laser entertainment system is rated as a Class IV laser product and manufactured
in accordance to EN 60825-1:2007. Avoid eye or skin exposure to direct or scattered
radiation. Wear protective goggles of suitable optical density if necessary.
!
If the laser is operated in a situation where health or property injury may occur the
operation must be stopped immediately.
!
The manufacturer and its distributors cannot be held responsible for any damages
caused by improper use or misuse of this KVANT laser system. The owner/user is fully
responsible for using this product in accordance to laser safety regulations of the country
or state where the system is being used.

What is a laser and how does it work?
What is a LASER?
The laser is a bunch of energy waves (streams of photons called radiation) with the same amplitude and
faze that are flowing in the same direction; meaning they are coherent – they stick together and form a
laser beam.
The width of a single wave is measured in nano-meters and defines the colour and visibility of the laser
beam. The visible spectrum of the human eye is roughly between 400nm and 700nm, going from violet
to a dark red colour. A human eye is most sensitive to a green light of around 555nm, meaning that a 1W
of green laser will always appear more visible than 1W of any other colour laser. 1W of quality laser light
is very powerful and although it doesn’t sound like much it can burn eye retinas, skin and clothes or even
start a fire!
What makes the laser visible?
Mainly it is the particles of dust in the air that the laser beam hits on its path. That’s why we “laserists”
use haze or smoke machines to make lasers more visible. Too much of the haze or smoke will kill it, but
the right amount will make all the difference between no show and a great show.
When outdoors, lasers mainly reflect off dust and mist in the air but due to unpredictable wind conditions
we can never make sure the hazers or smoke machines will be effective enough. And that’s why we use
high power lasers for outdoor shows – to substitute for the lack of dust, haze and smoke.
How far does it go?
Depending on the power output of the system and weather conditions, the laser can be visible for miles –
that is why we need to be cautious about aircrafts when performing outdoor shows. And if you get a
system that is powerful enough then yes, it can reach the Moon.
Colours
Standard full colour analogue lasers use three primary colours: Red, Green and Blue. By mixing those
together you can pretty much get any secondary colour:
Red +Blue = Magenta
Red +Green = Yellow
Green +Blue = yan
Red +Green +Blue = White
Of course the number and precision of the colours is determined by the modulation, stability and linearity
of the system. If the system is not stable enough, it will produce different colours every time it is used,
making it virtually impossible to match the colours of two systems at any one time. This is very often the

case with systems from far east manufacturers and with re-branded lasers that are being presented as
European makes.
Scanning System
A scanning system is essentially two tiny mirrors, each moving on X or Y axis. By working together they
can “scan” the laser beam in all directions. Once a shape is scanned more than 20 times per second, it
appears static to the human eye. So any shape drawn by a laser is actually produced by one single laser
beam running around like crazy. Every scanning system has a mechanical limit of how fast it can move
its mirrors and therefore how many points it can display at any one second and that is usually
represented in Points Per Second at a certain scanning angle, i.e. 8 degrees.

Laser Safety First!
Unless you are very competent with the use of lasers and about the laser safety, make sure you at least
follow these basic laser safety rules:
1. Never look directly into a laser beam.
2. Never look directly into laser aperture if the laser system is switched on.
3. Be aware that lasers can burn the eye retina, skin or cause fires if not used correctly.
4. Never perform Audience Scanning – that’s when laser beams and effects hit an audience directly.
Always project with the laser above audience head level – at least 3m above floor level.
5. When performing outdoors, avoid pointing the laser at aircrafts, buses, trains, etc.
6. Never leave the laser system unattended when it’s switched on.
7. Always check for reflective surfaces within the laser range – these can be very dangerous (i.e.
mirror behind the bar in a club could bounce the beam into bar attendant’s eye).
8. Never hesitate to use the Emergency STOP if you think there’s a fault within the laser system or a
potential danger to a person/object caused by the laser performance.
Before proceeding any further, please read the following safety page very carefully. It
could help you avoid dangerous and hazardous situations which could lead to serious
injury or property damage.
!
Any laser system classified as a Class 4 laser must be used with caution. If you are not
an experienced laser operator we would strongly recommend that you attend a laser
display safety course as soon as possible, and ideally before this laser system is used in
pubic areas. There are various places in Europe where you can attend quality training
and even a one day course will give you a good amount of valuable information to safely
start with.

Installation of the System
Please follow these rules during the installation:
1. Do not connect the device to power supply during the installation.
2. Mount the system only to mounting point that is strong, secure and away from places where non-
authorised person could get an access to.
3. Always make sure the system is properly tighten down and that it cannot get loose and
move as a result of sound vibrations, cable pull or similar. This is extremely important for
Logolas laser display systems. If Logolas is set to automated operational mode (i.e. laser
ON at 11pm/laser OFF at 5am), any visual check for the projection zone alignment will
probably not be possible!
4. Always use a safety rope.
5. Ensure that all the cables have enough leverage just in case they get caught.
6. Ensure that the system is placed at least 20cm away from walls or any other objects including
drapes etc.
7. Ensure that the system is placed well away from any heat sources including spotlights, moving
heads, radiators, etc. Make sure there is a sufficient air-flow around the laser system.
8. It is essential that the fan openings are never covered during the laser operation.
9. Always follow the Laser Safety Regulations of respective country where the laser is being used.
The manufacturer is not liable for damages or a injury caused by improper installation of
the system.
The installation should be carried by a qualified installer who should follow the Laser
Safety Regulations of respective country.

Logolas Control System
There is Moncha Lite laser control system inbuilt in every standard Logolas 1800 and Logolas 3000.
The communication (data transfer) between a control computer and inbuilt interface is done via Wi-Fi
network, where the network access point is provided by inbuilt wireless modem.
