UV Laser Marking is based on a high-precision process that is characterized by its particularly gentle effect on sensitive materials. In contrast to conventional laser marking processes that work with heat, the UV laser uses a so-called photochemical reaction - also known as "cold marking".
Photochemical Reaction (UV Laser)
UV Lasers with a wavelength of 355 nm directly excite the molecules on the surface of the material. This changes the structure of the material without generating any significant heat. This "cold" marking ensures fine, high-contrast and permanent markings without damaging the material.
Thermal Processes (e.g. CO2 or fiber lasers)
The material is melted, vaporized or discolored by the effect of heat. This can lead to melting marks, deformation or material weakening in heat-sensitive materials such as PVC, silicone or white polyamides.
UV Lasers in Industry - Precision That Sets Standards
UV Lasers with a wavelength of 355 nm are considered a high-end solution for industrial marking and micromachining. They enable contactless, gentle and high-precision processing that sets new quality standards in many industries.

Why UV Lasers? The Advantages at a Glance
1. Cold marking through photochemical reaction
In contrast to CO2 or Fiber Lasers, which work with thermal energy, UV Lasers generate markings through a photochemical reaction. This means: no melting, no deformation, no material damage - ideal for sensitive materials such as silicones, white polyamides, glass or medical plastics.
2. Maximum precision for the finest structures
Thanks to their short wavelength, UV Lasers enable extremely fine, high-contrast markings - even on the smallest surfaces. Whether DataMatrix codes, serial numbers or logos: The markings are razor-sharp and permanently legible.
3. Versatile in use
UV Lasers are suitable for a wide range of materials:
Plastics (also flame-retardant or without additives)
Glass & ceramics
Medical products
Electronic components
Packaging & labels
4. Hygienic & biocompatible
The virtually intact surface after marking makes UV Lasers zur ersten Wahl in der medical technology. The markings can be sterilized, are abrasion-resistant and biocompatible - perfect for catheters, insulin pumps or surgical instruments.
5. Process reliability & efficiency
Integrated camera systems enable automatic component recognition, marking alignment and quality control. This reduces rejects and ensures maximum process reliability in series production.
6. Sustainability & economic efficiency
UV Lasers work without consumables such as ink or labels. They are energy-efficient, low-maintenance and reduce the ecological footprint - a real plus point for sustainable production processes.
UV Laser Marking
UV Laser Marking is ideal for the gentle and high-contrast marking of sensitive materials such as ceramics, flame-retardant or biocompatible plastics. It is used wherever maximum precision is required - for example in automotive and aircraft construction, medical technology, electronics or extrusion processes. Thanks to its short wavelength, UV technology enables permanent markings without thermal stress and meets the highest requirements for legibility, traceability and material integrity.
UV, Fiber or CO2 Laser? The Big Comparison for Your Application
Choosing the right laser marking system is crucial for the quality, efficiency and sustainability of your marking processes. Whether for metals, plastics or organic materials – each laser source has its own specific strengths. Here you can find out which laser type is best suited to your material and your application.

- High marking speed
- Ideal for serial numbers, UDI codes, logos
- Perfect for automotive, aviation and mechanical engineering
CO2 Laser - The Classic for Organic Materials
Wavelength: 9,300 - 10,600 nm
Technology: Gas laser with high power
Ideal for: Paper, wood, cardboard, glass, PET, labels
CO2 lasers are particularly suitable for marking organic materials and packaging. They work thermally and create markings by removing material or changing color.
Advantages:
- Ideal for the packaging industry
- High cutting quality for organic materials
- Versatile use for engraving and marking

FAQ
A UV Laser is an industrial marking laser with a wavelength of 355 nm. It works in the ultraviolet spectrum and creates markings through a photochemical reaction - without any thermal stress. The result: razor-sharp, permanent markings that are gentle on materials.
UV Lasers are ideal when maximum precision with minimum heat input is required - e.g. when marking sensitive plastics, glass, ceramics or medical products.
UV stands for "ultraviolet" - a region of the light spectrum with a particularly short wavelength. This property enables so-called "cold marking", in which the material is not thermally stressed.
Medical technology: catheters, insulin pumps, surgical instruments
Electronics: printed circuit boards, connectors, sensors
Automotive & aviation: cables, hoses, flame-retardant plastics
Packaging & consumer goods: plastic packaging, labels, glass containers
Silicones, white polyamides
HDPE, PP, PVC
Glas, Ceramic
