STEERED BEAM LASER OPERATION
3 main parts:
• Laser tube – produces a beam of laser light
• Mirrors – 2 motorised X-Y mirrors reflect the beam
• Lens – the lens focuses the beam to a fixed point on the product.
Notes:– For moving products the mirrors will
‘chase’ the product– Linx lasers are designed to find the most
efficient coding path for either stationary or moving product.

MORE RELIABLE
Reliable laser tube
• A longer tube life is not just the result of the quality of thetube itself
• Tube life is also prolonged as a result of an efficient use of thelaser energy and also careful machine design to ensure thatthe tube is kept at an optimum temperature
• Linx provides a 2 year warranty* (tube only).
Optimum laser power to ensure longevity of tube
• By specifying the right laser, head and lens we are making the most efficient use of the laser tube, so it lasts longer!
• A bit like running a car:– if you drive 100km/h in 2nd gear it will overheat, you will
spend more on fuel and eventually breakdown; – if you drive 100km/h using the correct gears for your
journey, the car will last much longer!
Efficient cooling system
• Some competitor laser coders do not have an efficient cooling system which means that the laser tube runs above itsoptimum temperature. This reduces laser output causing poorquality codes, which can lead to higher maintenance costs(tube replacement/laser service).
24/7 operation without the need for manual intervention
Robust stainless steel design with an IP65 option
• Durable equipment suitable to the most challenging productionenvironments.
Benefits
• Minimal running costs and downtime.
*Tube life may vary according to application.
MORE INTUITIVE
Intuitive to use
• Large WYSIWYG display showsclearly the selected message toprint
• No complex menus or parameters
• At-a-glance status reporting enables the user to quickly understand laser status
• Easy to enter and select Jobswith message preview
• Quick access operator tool bar.
Benefits
• Minimal operator training, limiting operator mistakes and increasing productivity.

Intuitive to set up
• A unique set-up wizard removes the complexity of implementation and guides users through configuration step-by-step.
Benefits
• Installation can be quickand error free so it meansless downtime for the customer.
Tell us about your application, give us a product sample, andwe’ll give you the right solution.
• What message do you want to code (code complexity)?
• What substrate do you want to mark on?
• What is your (maximum) line speed?
• What is the (minimum) product pitch?
Depending on the laser configuration, a Linx 10W could outperform a competitor’s 30W, or a 30W could replace a 50W.Our rigorous sample marking process ensures the right laser-head-lens-tube combination is tailored to the customer application, ensuring the laser energy is used efficiently and prolonging theoverall lifetime of the laser.

When you visit a customer they will want to know whether the Linx SL102 and SL302 are suitable for their application.
In order to understand whether your customer’s application isgoing to be possible, you need to know two things:
1. How long is it going to take to mark the product?(Time to Mark)
2. How much time do I have to do it in? (Available Time)
In order to answer these two questions, you need to ask the customer for some additional information. To determine the ‘Time to Mark’, you need to know:
• Code complexity, because writing more information in a code takes longer than writing less information
• Substrate type, because some substrates are easier to markwith a laser than others
• Marking field size, because a bigger field gives you a longertime to write (this is determined by sample marking)
• Spot size / energy density, because more energy per area on thesubstrate takes longer (this is determined by sample marking).
In order to determine the ‘Available Time’, you need to know:
• Line speed, because the faster the line the less time is available
• Product pitch, because the closer the products are to eachother, the less time available.
Understanding ‘Time to Mark’ and ‘Available Time’ will help you sell the Linx SL102 and SL302 because they can do applications that other competitors are unable to.
So, let’s see what this means in practice...

If time required to mark is less than, or equal to, the time that is available to mark, then the Linx laser is suitable. Because we have one of the most versatile coders in the market, in most cases the Linx SL102 and SL302will be the right laser coder for your application.
In most cases for the Linx SL102 and SL302, the ‘Time to Mark’ is lessthan or equal to the ‘Available Time’.

on the scale, you will be provided with a starting pointFor example:- Substrate: Paper- Line Speed: 25 M/Min- Code Complexity: 1 line (10 Char)Which Laser?: 10W probably suitable (pending sample marking)
– This page is to be used as a guide only for determining the likely laser for your customers application. In order to determine the optimal laser configuration, sample markingshould be performed.
Example
There are three factors which help you decide on the correct power laser for an application. These are substrate,line speed and code complexity.
SUBSTRATE
• Heat sensitive paper• Reactive coating (e.g Datalase®)• Paper• Colour coated paper• PVC• Colour coated card• PET• Painted metal• Glass• HDPE/LDPE
LINE SPEED
• <40m/min• 41-100 m/min• 101-300 m/min• 301+ m/min
CODE COMPLEXITY
• 3 characters• 7 characters• 1 Line 10 characters• 2 Lines 10 characters• 3 Lines 10 characters• 4 Lines 10 characters
Notes:– Larger characters will increase the complexity and the
marking time of the code– Linx lasers cannot code bare metal, hot glass and base HDPE.

Sample marking is the critical component of any successfullaser sale and should not be omitted. Good sample markingwill determine the most cost effective solution whilst ensuring the highest quality code and prolonging laser life.
The sample marking process will confirm the correct basic configuration for an application – laser power, head and lens option.
The Sample Marking Request Form should be completed in full and returned to either your local sample marking function or preferably Linx sample marking lab.
The Sample Marking Request Form can be downloaded from ExtraLinx following this path:
Customer Service Tab > Commercial Information >Narrow search by Laser coders > Search ‘Sample’
Key information needed when visiting the customer site for accurate sample marking is:
• Maximum linear line speed in metres/minute or feet/minute
• Minimum product pitch – the measurement from the leading edge of one product to the next
• Code format: character size, number of characters, number of lines of text
• Code position on product
• The sample marking lab needs samples to produce on before defining the optimal configuration. Please try to collect at least 10 samples
• Samples are completed in the order in which they arrive at Linx, and will be ready for despatch to the Distributor within one week of receipt by Linx.
SAMPLE MARKING
Conveyor Direction
Product ProductPitch
The head and lens configuration depends on:
• An appropriate spot size for the size of characters specified by the customer’s code
• Required mark field size
• Achievable marking distance between marking head and product during installation
• Energy density at product
• Line speed and product pitch variables.
Note:– Sample marking is tasked in finding the best head and lens
configuration that meets the customer speed, pitch, substrateand code complexity requirements.

HEAD AND LENS CONFIGURATION DETERMINE THE SPOT SIZE (BEAM DIAMETER)
The spot size determines the energy density on the product.
For example:
The 0.2mm spot is half the diameter of the 0.4mm spot and has x4 more energy density!
For example: an application that needs 80% laser intensity with the 0.4mmspot size would need only 20% with the 0.2mm spot size.

MarkingField
Notes:– For stationary marking only, sample marking would be
required to determine whether the code actually fits into themarking field
– For marking moving products, sample marking would need toconsider the marking field length in direction of movement,line speed, and the minimum product pitch
– The longer the marking field in the direction of movement, the longer ‘available time to mark’, but more time is needed for the galvos to return to their start position to code the nextproduct so the minimum pitch value increases.
Marking field is the maximum surface area that can be marked by a particular head-lens combination.

Notes:– The marking distance varies as each lens has a different
focal point– The laser beam must be in focus on the product in order to
generate an effective mark– Marking distance is an important piece of information in
integrating the laser into the customer production line– Linx offers a range of accessories: Beam Extension Units
(BEU) and Beam Turning Units (BTU) to work around production line constraints and make sure the laser beam is in focus on the product.

GUIDE LINES TO ACHIEVE CLASS 1 WITH GUARDINGFor industrial production processes, a laser safety enclosure will need to be built around the marking point of the laser outputbeam. Safety guards prevent access to the laser beam and alsocontain accidental radiation caused by reflection. If the guard canbe opened an interlock switch will need to be incorporated into theinstallation. The enclosure will transform the Class 4 (IV) laser to Class 1(I) and can be safely used in a production environmentwithout personal eye protection.
Recommended construction:• 10mm polycarbonate sheet• Interlocked access door• Restrict access to marking area by operators• Restrict direct view of lens• Laser stop (ceramic tile) opposite lens.

Description Hazard potential
Class 1 (I) laser products are defined as safe in normal operationsunder reasonably foreseeable conditions, including direct viewing ofthe laser beam with optics that could concentrate the laser outputinto the eye. In addition to some intrinsically low power lasers andlaser products, Class1 (I) laser products also include embeddedproducts that totally enclose a higher class of laser, for example, CD players and most industrial laser processing machines.
No risk toeyes or skin
4 (IV) Class 4 (IV) laser products are defined as those for which direct exposure of the eye and skin is hazardous and scattered laser lightmay be hazardous to the eyes. Such lasers are also a fire hazard.
High risk toeyes or skin
If the coder is installed correctly and used according to the operating instructions, the system becomes a Class 1 (I) lasersystem. The coders contain Class 4 (IV) lasers, and the installationmust use the correct guards and interlocks to make a Class 1 (I)laser system. The system becomes a Class 4 (IV) laser systemduring any procedure that requires the removal of covers, guards or safety interlocks.
