Lorsque vous utilisez un graveur laser, matching the right laser source with the proper lentille de champ isn’t just a technicality—it’s the secret to maximizing your engraving precision, pouvoir, et la vitesse. Que vous travailliez le métal, Plastique, ou céramique, 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:
| Type de laser | Longueur d'onde | Idéal pour | Example Materials |
|---|---|---|---|
| CO₂ Laser | 10,600 nm | Organic materials | Bois, acrylique, cuir |
| Laser à fibre | 1,064 nm | Les métaux & plastiques durs | Acier inoxydable, aluminium, abdos |
| Laser UV | 355 nm | Heat-sensitive & fine detail work | Plastique, verre, céramique |
Chaque laser source emits light at a specific longueur d'onde, 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)
Le lentille de champ, also called an F-theta lens, determines your engraving area and focus characteristics. Important factors include:
- Distance focale (par exemple., 100millimètre, 200millimètre): Shorter focal lengths = smaller working area, tighter focus = higher detail.
- Taille du point: 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
| Type de laser | Typical F-Theta Lens | Cas d'utilisation |
|---|---|---|
| Co₂ | 63.5mm or 100mm | Cutting/engraving wood or acrylic signs |
| Fibre | 160mm or 254mm | Deep metal engraving or color marking |
| UV | 110mm or 150mm | QR code etching on plastics, IC chips, glass bottles |
Conseil: For the ComMarker Omni 1 Graveur laser UV, 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
- Compatibilité des longueurs d'onde
A lens designed for 1064nm (fibre) won’t transmit 355nm (UV) effectively. Make sure your lens matches your laser source wavelength. - Engraving Area vs. Précision
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. - type de materiau
- Métal: Laser à fibre + 254mm lens for coverage or 160mm for depth.
- Plastique: Laser UV + 110mm lens = crisp, high contrast.
- Organic: Co₂ + 63.5mm = fine details on wood or leather.
Recommended Setups for Beginners and Professionals
| Matériel | Meilleur type laser | Ideal Lens | Cas d'utilisation |
|---|---|---|---|
| Acier inoxydable | Laser à fibre | 160millimètre | Deep engraving, outils |
| Plastic Products | Laser UV | 110millimètre | Numéros de série, Codes QR |
| Verrerie | Laser UV | 150millimètre | Logos on bottles |
| Leather Tags | CO₂ Laser | 63.5millimètre | Image de marque personnalisée |
