Alegerea corectă laser source is one of the most critical decisions when buying a gravator cu laser. Whether you’re customizing wood gifts, marking metal tools, or personalizing glassware, your engraver’s performance—and limits—are defined by the type of laser it uses. În acest articol, we’ll break down the core types of laser sources (Co₂, fibră, and UV), explore their differences in wavelength and power, and help you decide which one suits your real-world needs.
What Is a Laser Source? (CO₂ vs Fiber vs UV)
A laser source in a gravator cu laser is the component that emits the high-energy beam used to mark or cut materials. Different source types use different physics—and that greatly affects what materials they can engrave.
| Tip | Lungime de undă | Cel mai bun pentru | Common Use Cases |
|---|---|---|---|
| Co₂ | 10,600 nm | Organic materials like wood, Piele, acril | Crafting, semnalizare, ambalaj |
| Fibră | 1064 nm | Metalele, materiale plastice dure | Metal tags, unelte, piese industriale |
| UV | 355 nm | Heat-sensitive materials like plastic, sticlă, ceramică | Precision marking, Electronică, dispozitive medicale |
✅ Sfat: The shorter the wavelength, the better it handles fine, heat-sensitive, or brittle materials.
Why Wavelength Matters: Matching to Materials
The lungime de undă of the laser determines how deeply and cleanly it interacts with specific materials.
- CO₂ lasers (10,600 nm) are absorbed well by non-metals, making them ideal for engraving wood, acril, hârtie, și piele.
- Laser cu fibră (1064 nm) penetrate metals effectively due to higher photon energy at that wavelength.
- lasere UV (355 nm), like those used in the ComMarker Omni 1, are absorbed on the surface without heat buildup, making them perfect for plastics, sticlă, și ceramică.
Power vs Efficiency: Does Higher Wattage Mean Better Engraving?
Not always.
- Higher wattage means faster marking or deeper engraving—but only when paired with the right wavelength and lens system.
- A 5W UV laser can outperform a 20W fiber laser on plastic or glass, because the UV wavelength interacts better with those materials.
Here’s an example from real tests using the ComMarker Omni 1 Gravoare cu laser UV:
| Material | Sursa laser | Power Used | Rezultat |
|---|---|---|---|
| White ABS Plastic | UV (355nm) | 5W | High-contrast black mark, no melting |
| Oţel inoxidabil | UV (355nm) | 5W | Light surface mark only |
| Lemn | Co₂ (10,600nm) | 40W | Deep and wide engraving |
Choosing the Right Laser Source: What to Consider
When deciding which gravator cu laser to buy, focus on:
- Material types you work with most
- Engraving depth vs. viteză (Do you need surface marks or deep cuts?)
- Level of detail (coduri QR, tiny text, fine lines? UV wins here)
- Buget (CO₂ lasers are usually more affordable for hobby use)
Real-World Use Case Examples
- A jewelry crafter working with gold and silver → Go for a laser cu fibră
- A DIY creator customizing tumblers and wood signs → Best with a CO₂ laser
- A startup marking logos on phone cases, ochelari, and ceramic mugs → Choose a Laser UV, ca Omni 1
