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 = Cyan
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
Kvant spol. s.r.o. Logolas series - v61216
Page 4 of 29
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.

Scanning System
The product warranty does not cover the damages to the scanning system caused by improper
use of the scanning system or by incorrect programming. Therefore it is essential to understand
how the scanning works and where are the limits of it. In this manual we will explain only the
basics of it but it is the responsibility of every user to educate themselves so they can avoid
damage being caused to the scanning system and costly repairs.
A laser beam comes from a laser module and hits the two moving mirrors of the scanning system. These
mirrors are mounted on the scanner shafts and are moved by the scanner rotors, one on X and one on Y
axis.
An effect such as tunnel (circle) is displayed by a repetitive mechanical movement of the scanners. For
each scanning system and effect, there’s a maximal scan rate that is defined by mechanical load,
scanner mirror size and weight, complexity of displayed picture and size of the projection (an angle
under the laser beam is being projected). A different scanning systems have different scan- rate limits. It
is essential to operate the scanning system at scan-rates within its maximal limit at all times to prevent it
from overload damage.
How to establish correct Scan-rate and maximal number of points in an effect
Each effect (picture) contains a different number of graphical points which defines the actual shape of
the effect. The more points an effect contains, the lower the maximum scan rate will be in relation to the
scanning angle.
Kvant spol. s.r.o. Logolas series - v61216
Page 9 of 29
As an example we’ll work with the star effect shown below and with the parameters of quality scanning
system:
Let’s say the star effect is made of 300 graphical points (including non-visible blanking points) and we
know that the maximal scan-rate of our scanning system is 35kpps @ 8 degrees (= 35.000 points per
second at 8 degrees projection angle). We also know that we display the star 35 times per second which
is a default frame rate of the control software we are using.
So we need to display 300 points 35 times per second = 10.500 pps. This means that we could display 3
of these stars beside each other within one single laser effect and that it would be quite close to the
scanner limit (3 × 10.500 = 31.500pps). This however applies ONLY if the scanning angle is not more
than 8 degrees on both axes! If we start to increase the size of the projection (scanning angle) it is
necessary to either lower the number of points within the effect or drop down the scan-rate in the control
software (FPS) to a safe level – which may result in flicker.
From the example above we can also determine how many points this scanning system is able to project
if the scanning angle is not more than 8 degrees:
35.000 points / 35 Frames Per Second = 1.000 pps. This is the absolute maximum of how many points
we should be using when programming an effect if the scanning angle is not more than 8 degrees.
In the following pictures you see the same star effect scanned at different scan rates at full scanning
angle (60 degrees).
Picture 1: the scan rate and/or number of points is too low. The corner points are more visible than the lines between them and the whole effect flickers. The scan-rate and/or number of points needs to be increased. Picture 2: the scan-rate and/or number of points is about right. The whole effect has more or less the same intensity and does not flicker. Picture 3: further increasing of the scan-rate and/or number of points results in the effect starting to distort, firstly around corners only. This indicates that you are exceeding the maximal scan rate of the scanning system! If you operate the scanning system at scan-rates higher than the maximum scan-rate of the scanning system the scanners will get damaged irreversibly due to overheated coils damaging rotor magnets.

Maintenance
Aperture Window
To clean the aperture output window use a soft cloth and medical grade isopropyl alcohol.
Internal Optics
The cleaning of the internal optical components should be performed by an authorised technician only.
Incorrect techniques or wrong choice of chemicals used for cleaning could cause serious damage to the
laser system. Due to the fact that the optical compartment is split and sealed from the rest of the laser
system it shouldn’t be necessary to perform this procedure more often than once a year.

System Overview
KVANT Logolas is a full colour, semiconductor diode laser system designed primarily for a small-scale
professional laser graphic displays.
When operated correctly and in the right conditions the Logolas laser system is able to deliver a strong
performance on up to 200m projection distance. The Logolas can display virtually any colour within the
basic RGB palette and its secondary mixed colours including white.
The system is air-cooled and designed so that there is no airflow going through the optical compartment
of the system. This ensures that all important optical parts of the system stay clean for longer, keeping
the maintenance time down to a minimum. This is a real advantage for all the applications where lots of
dust or haze is present on a daily basis.
This laser is IP rated to IP65, meaning that it is rain-proof.

2. Wi-Fi antena.
When you access the internal control board, you will find the following control features:
Scan-fail safety mode selector and Scan-fail status indicator.
There are two modes in which the Scan-fail detection system works:
SCANNER – the system controls the movement of both scanners. If there is no movement it
switches the laser emission off and keeps it off until there is a movement on both scanners
detected.
INPUT – the system checks for a difference between the input signal that goes into the laser
system and the movement of the galvo motors. If the system detects that there’s a difference
between these two signals (meaning that scanning system is faulty), it will switch the laser
emission off.
Kvant spol. s.r.o. Logolas series - v61216
Page 19 of 29
Please note, in the INPUT mode the safety circuit sometimes kicks in if the scanned effect is too
small.
Main controls. If required, you can use these control pots to adjust the size and position of master
projection zone. The power output of each of three basic colours (RGB) can be manually adjusted by
turning the corresponding pot to left or right. Normally, all the colours are adjusted in the laser control
software and these pots are mainly used when taking power measurements or when performing the
beam alignment procedure.
Please note that in most countries it is required by law to have a fully working Emergency STOP in place for every laser system used. If you use supplied interlock connector to defeat the safety interlock you must have another method in place to be able to kill the laser output instantly in case of emergency.

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

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.

Beam Alignment [Logolas 1800]
1. To open the internal compartment of the laser system undo the latch and swivel the cover around
the front end hinge.
2. Decompress the micro-switch at the back top edge of the chassis and tape it down so it stays in
ON-state position. This will allow the laser operation with top lid open.
3. Power up the system as normal.
4. Firstly, it is necessary to align a colour with the longest beam path between the laser module
output and the scanning system in a way so it hits the exact centre of the bottom scanning mirror –
in this case it is the blue laser beam.
Create a blue beam effect (point) and check visually whether the beam hits the exact centre of the
bottom scanning mirror.
If not, follow the diagram on the next page to adjust the beam path accordingly (step 1 on the
diagram below).
Although KVANT uses the latest technology to protect all the critical components inside this laser system against Electrostatic Discharge, the semiconductor laser diodes within this system are extremely vulnerable to it. This is due to some of the electronic components being exposed when the top cover is taken off. If you decide to proceed with the Beam Alignment process yourself, it is absolutely essential that all the common ESD protection rules are strictly followed. We don’t accept any responsibility for Electrostatic Discharge damages to laser diodes caused by customer.

5. Create a full size cyan circle (static tunnel effect) and check whether the green circle overlays the
blue circle all the way around the shape.
If not, adjust the beam path of the green circle accordingly (step 2 on the diagram above).
6. Create a full size yellow circle (static tunnel effect) and check whether the red circle overlays the
green circle all the way around the shape.
If not, adjust the beam path of the red circle accordingly (step 3 on the diagram above).
7. Create a full size red circle (static tunnel effect) and check whether the 2nd red circle overlays the
1st red circle all the way around the shape.
If not, adjust the beam path of the 2nd red circle accordingly (step 4 on the diagram above).
8. Finally create a full size white circle (static tunnel effect).
If the alignment procedure was done successfully you can see all the colours nicely overlaying
each other, resulting in even, bright and sharp circle like the one on the picture below.

3. Power up the system as normal.
4. Firstly, it is necessary to align a colour with the longest beam path between the laser source and
the scanning system in a way so it hits the exact centre of the bottom scanning mirror – in this
case it is the red laser beam (made of 4 individual red beams R4 – R1)
5. Create a red beam effect (point) and check visually whether the beam hits the exact centre of the
bottom scanning mirror.
If not, follow the diagram on the next page to adjust the beam path accordingly (step 1 on the
diagram below).
6. Create a full size red circle (static tunnel effect) and check whether the red circles of all R4, R3,
R2 and R1 overlay each other all the way around the shape.
If not, follow the diagram below to adjust the beam path accordingly (step 1 & 2 on the diagram).
Although KVANT uses the latest technology to protect all the critical components inside this laser system against Electrostatic Discharge, the semiconductor laser diodes within this system are extremely vulnerable to it.
