Gravotech -  Laser series : Hybrid, CO2 and green

GREEN laser

GREEN laser, Integrated laser marking system - mark highly reflective materials and sensitive plastic materials.
GREEN laser marker is designed for complex and cold markings on materials not reactive to other wavelengths. In addition, the GREEN laser has a small spot diameter that offers unsurpassed micro marking quality and accuracy on a wide range of materials.
  • Cold laser marking
    Cold laser marking refers to marking and treatment carried out with minimal thermal stress. Laser beam concentration allows marking without generating heat into parts, avoiding any burning or damage. This marking doesn’t alter the material and is an ideal solution for marking soft materials and sensitive components.
  • Ultra-high-definition micro marking
    Gravotech has developed green laser engravers that guarantee small and fine markings, it offers a fine spot size of 20 μm and micro markings with exceptional resolution while limiting thermal stress on the material. Small 2D Datamatrix, detailed logo, precise removal of thin layers of coating: the GREEN Series can meet all of your application challenges.
  • Mark the impossible
    Its versatility is almost unrivaled. This range uses a 532 nm wavelength to mark materials that would not normally react to infrared wavelengths: from rough to the most transparent plastics, reflective metals (copper, silver, gold), ceramic, cardboard, wood.

Technical Specifications

Laser source
DPSS (Diode Pump Solid State) source

Available power range
5W, perfectly suited for contrasting marking on plastic

High absorption rates in materials that don’t react well with IR wavelengths
Some plastic materials (colored plastics, acrylic and polymer materials) and materials that reflect IR light such as gold and copper.

Laser classification
Class 4 Laser system, possibility to switch in Class 1 for integration on a station or equipped with Mini-Inline module.

Monobloc design, easy integration
No sensitive cable connections in system integration.

Thanks to its integrated HMI display, it provides access to self-diagnostic, updates, history of faults, maintenance functions and simplifies the implementation in all positions and visualization of tasks for the operator.

Highly communicative laser
Green laser markers compatible with a wide range of communication protocols:

  • Ethernet TCP/ IP,
  • RS232,
  • standard 8 I / 80,
  • Dedicated I/O via DB-37

and optional industrial communication protocols like Profinet & Ethernet IP.

Robust laser system

  • Working temperature up to 40°C
  • Built-in and washable filter for air cooling, protection against scratches and deposits.

circuit board components identification permanent marking

All electrical devices are using plastic with specific properties: - Insulating properties, not to conduct electricity. - Fire resistant through the use of special flame retardant additives. - Can withstand high temperature. These technical plastics with additives do not react to standard IR laser (1064 nm). GREEN laser works perfectly and offers a contrasted marking to replace inkjet and label solutions. You can use it for the CE & normative marking, technical specifications, pins & terminal references, etc. This GREEN laser marker saves time and money as it requires no consumables and is a high productivity and eco-friendly solution.

laser engraved charms

The GREEN series laser reacts perfectly with precious metals such as gold & silver but also on other highly reflective materials such as copper, stainless steel, and brass. The very high absorption rate of 5320 nm wavelength gives a contrasted marking resistant to corrosion. The risk of blackening and smearing is reduced by the low heat delivered by the laser beam. You have no waste of materials as the laser marking is very thin and localized. It is also perfect to mark on thin metal sheets, there is no deformation due to heat with the laser. Market Examples: Stores & Jewelry, traceability of precious metals such as gold and silver, traceability of medical devices

Embedded software on laser marker

Totally independent, laser green engraver works without a PC and automatically generates the data to be identified (multiple format timestamps, variables, counters, offset codes) directly on your part. Its onboard electronics make this laser an ultra-communicative solution with your environment, thus centralizing all the information from your PLCs and database in real-time and thus increasing your productivity by saving time

Lasertrace : our marking and identification software

Lasertrace is the software dedicated to the creation of marking files and to the piloting of our marking lasers. Its simple and intuitive interface allows easy composition of your marking files, text, logo, 2D code... You can define your marking sequence according to directions: the actions (marking blocks) to be carried out, the execution procedure and the possibility of setting up a wide choice of transitions (output activations, camera blocks, variables, etc.).

Vision manager - marking control

The vision manager package helps you read codes and texts during and after the marking process, to ensure that the marking has been done properly and keep 100% traceability of your products. - Efficiency and performance: reading camera with lighting, auto-focus system and protective lens. - Easy to use: You are just a few clicks away from complete control of 1D/2D codes and your text (OCR fonts). - Gradation of the marking: Quality control of the readability of the codes (Grade). - Quality checking: sending status information and history to the PLC, activation of alarms, activation of the system to reject the faulty part.
