Product Overview
The wavelength of the ultraviolet laser is 1/3 of the basic wavelength (1064nm), and it is a laser in the ultraviolet region, so it is called “ultraviolet laser printer”. In addition, it is also known as THG (Third Harmonic Generation) laser. The fundamental wavelength is converted to a wavelength of 532 nm plus the basic wavelength through a nonlinear crystal, and then converted to a wavelength of 355 nm by another single crystal. The absorption rate of each material is very high, and because it can be marked and processed without heat stress, this type of marking is called “cold marking”.
The wavelength of the light greatly affects the spot diameter of the laser. Since the UV wavelength (355 nm) is 1/3 of the basic wavelength (1064 nm), the spot size can be concentrated even in a small area, making it possible to mark even in a confined space.
Product Advantages
Industry vane
PET packaging producers are increasingly using “thin-walled” PET in an attempt to reduce costs and waste. This creates difficulties for laser marking, as thinner materials can burn through. Choosing a UV laser printer solves this challenge by producing alternative marking effects.
At the same time, in the context of strengthening the laws and regulations related to the use of drugs, there are also increasing cases of switching from ink to laser marking.
High-density polyethylene (HDPE) bottles continue to be one of the premier packaging solutions for pharmaceutical products, requiring labeling on the bottle body to facilitate product tracking. UV laser printers can mark dark, long-lasting, high-resolution codes on a light-colored HDPE background that is also visually readable.
Inhibits thermal damage
Photolysis treatment inhibits damage
UV lasers have a large energy of photons, and can be used to directly cut off the intermolecular bond. Therefore, without heating the surface, it is possible to perform marking and processing to suppress damage.
Photolysis treatment inhibits damage
It also has a high absorption rate for materials with high reflectivity, such as gold, silver, and copper, and does not generate unnecessary thermal stress. As a result, it is possible to suppress the generation of soot and burrs without damaging the surface state, and to achieve high corrosion resistance for marking and processing.
Photolysis treatment inhibits damage
As electronic parts become smaller year by year, the thickness of the packaging resin part is also decreasing. If a basic wavelength laser (1064nm) is used, it may pass through the encapsulation resin and cause internal damage. If a UV laser (355nm) is used, it can suppress the penetration of the laser into the interior with a high absorption rate.
Ultraviolet laser coding case
UV laser marking (355nm) is ideal for heat-sensitive materials like food packaging, pharmaceuticals, silicon wafers, and LCD screens. Its short wavelength breaks molecular bonds directly, enabling precise marking without thermal damage.
Marking on metal, plastic, ceramics, glass, rubber, textiles, masonry, corrugated cardboard, flexible films, foils, labels and other materials.
It delivers high precision, efficiency, and fade-resistant marking with low noise and energy consumption—ideal for food, pharmaceutical, and consumer goods industries, supporting Industry 4.0 production.
Product Applications
The main application scenarios of UV laser coding machine:

Tetum Russellis is an acronym for “Leyteamplifi Cation, Bisti Murat de Emision, Ben Radiateon”.
Excellent monochromaticity (the beam consists of a purely single wavelength);
Excellent directivity (the beam consists of parallel light waves that do not diffuse when propagating);
High coherence (all the light waves of the beam are the same with each other).
[/su_spoiler]
[su_spoiler title=”What is the difference between a normal light and a laser beam?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Lasers emit beams of light with high directionality, i.e., the light waves that are composed of light travel in a straight line and do not diffuse. The light waves emitted by ordinary light sources diffuse in all directions.
The light waves within the laser beam are all of the same color (this property is called monochromacy). Ordinary light, such as that emitted by fluorescent tubes, is generally a mixture of several colors of light that appears white.
When light waves within a laser beam propagate, they oscillate in perfectly synchronized peaks and troughs, a property known as coherence.
[/su_spoiler]
[su_spoiler title=”Is laser visible light?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
The laser itself is invisible. Due to the highly directional nature characteristic of lasers, we cannot see the path of the beam. Usually we can only see the diffuse reflection and reflection of the laser on any object. In an environment where there is mist or particles in the air, we can see the path of the beam because the light is diffusely reflected and reflected by the particles.
[/su_spoiler]
[su_spoiler title=”Is the laser code permanent?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
One of the main features of laser markers is that they can print semi-permanent printed images. Since the laser marker physically processes the surface of the target, the printed image cannot be removed as easily as the image printed with ink. This feature has led to the increasing popularity of laser markers in recent years in terms of security applications (anti-counterfeiting).
[/su_spoiler]
[su_spoiler title=”Is it possible to look directly at the laser?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Never look directly at the laser, a laser that is specularly reflected, or a laser that is diffusely reflected. If the eye is directly exposed to lasers, it can lead to blindness. All laser products use 4 types of lasers, which cannot directly contact the body and skin.

[su_spoiler title=”What maintenance does a laser marker need?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
The maintenance-free laser marker is one of the main advantages of this product. If the lens surface becomes dirty, it should be cleaned, as a dirty lens can degrade the print quality or cause some parts of the printed image to be missing.
[/su_spoiler]
[su_spoiler title=”What is the best way to clean the lens?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Swabing in a circular shape from the center of the lens outward is the most effective method. Never use a dry cloth to wipe the lens, as this may scratch the lens or wear off the protective coating.
[/su_spoiler]
[su_spoiler title=”Is laser marking affected by device vibrations?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Laser markers use precise optical control. For this reason, if vibrations occur during marking:
The marking coordinates may be offset;
The text may be distorted;
Other problems may arise as well.
If environmental vibrations affect the laser marker, use an anti-vibration bracket or take other precautions to eliminate the vibrations.

[su_spoiler title=”Do you need to replace your air filter when it gets dirty?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Yes. When an air filter becomes dirty, it needs to be cleaned or replaced. If the condition of the filter is ignored, the cooling performance will be reduced, which may reduce the laser output or cause damage.
[/su_spoiler]
[su_spoiler title=”Can I engrave on a moving target?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Yes, the laser marker is able to adjust the position of the laser to follow the product and thus mark on a moving target. This function can be automatically set for both constant and variable speed lines.
[/su_spoiler]
[su_spoiler title=”Does engraving on glass cause cracking?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
The results depend on the type of glass used. Since glass is transparent, it is usually marked using the heat generated by a CO2 laser. For heat-resistant materials such as quartz glass, clear, crack-free engravings are produced. In contrast, applying heat to soda-lime glass can cause fine wrinkles, so repeated scans must be performed with a low power setting.
[/su_spoiler]
[su_spoiler title=”How much does it cost to run?” open=”no” style=”simple” icon=”plus” anchor=”” anchor_in_url=”no” class=””]
Zero cost, in principle, there is no cost other than the daily cost of electricity. The use of photolithography makes the laser marking machine have the two characteristics of “no consumables” and “long service life”. Laser markers significantly reduce many of the steps of material management and eliminate the cost of ink and labels.
