Når du bruker en lasergraver, matching the right laser source with the proper feltlinse isn’t just a technicality—it’s the secret to maximizing your engraving precision, makt, og hastighet. Whether you’re working with metal, plast, eller keramikk, understanding how these two core components interact will directly impact the quality of your results. This guide will help you pair them effectively based on your material and application.
Understanding the Laser Source and Its Role
Before diving into lens selection, let’s review the three most common laser sources:
| Laser type | Bølgelengde | Best for | Example Materials |
|---|---|---|---|
| CO₂ Laser | 10,600 nm | Organic materials | Tre, akryl, lær |
| Fiberlaser | 1,064 nm | Metaller & hard plast | Rustfritt stål, aluminium, ABS |
| UV laser | 355 nm | Heat-sensitive & fine detail work | Plast, glass, keramikk |
Each laser source emits light at a specific wavelength, which affects how well it is absorbed by the target material. This is crucial because poor absorption means weak marking or even surface damage.
Choosing the Right Field Lens (F-Theta Lens)
De feltlinse, also called an F-theta lens, determines your engraving area and focus characteristics. Important factors include:
- Brennvidde (f.eks., 100mm, 200mm): Shorter focal lengths = smaller working area, tighter focus = higher detail.
- Spotstørrelse: Smaller spot size = higher precision, but less depth.
- Distortion: A good F-theta lens minimizes edge distortion in large working fields.
Typical Pairings for Efficiency
| Laser type | Typical F-Theta Lens | Bruk sak |
|---|---|---|
| Co₂ | 63.5mm or 100mm | Cutting/engraving wood or acrylic signs |
| Fiber | 160mm or 254mm | Deep metal engraving or color marking |
| UV | 110mm or 150mm | QR code etching on plastics, IC chips, glass bottles |
Tupp: For the ComMarker Omni 1 UV lasergraver, a 110mm field lens gives excellent accuracy on small plastics, while a 150mm lens is better for glass or ceramic surfaces.
Matching Considerations That Matter
- Wavelength Compatibility
A lens designed for 1064nm (fiber) won’t transmit 355nm (UV) effectively. Make sure your lens matches your laser source wavelength. - Engraving Area vs. Presisjon
Larger field lenses cover more surface area, but with a larger spot size. If you’re marking fine logos or QR codes, use a smaller lens. - Materialtype
- Metall: Fiberlaser + 254mm lens for coverage or 160mm for depth.
- Plast: UV laser + 110mm lens = crisp, high contrast.
- Organic: Co₂ + 63.5mm = fine details on wood or leather.
Recommended Setups for Beginners and Professionals
| Materiale | Best Laser Type | Ideal Lens | Bruk sak |
|---|---|---|---|
| Rustfritt stål | Fiberlaser | 160mm | Dyp gravering, verktøy |
| Plastic Products | UV laser | 110mm | Serial numbers, QR -koder |
| Glassvarer | UV laser | 150mm | Logos on bottles |
| Leather Tags | CO₂ Laser | 63.5mm | Tilpasset merkevarebygging |
