Hgnova 15 Pcs Fiber Laser Protective Lens
Diameter 27.9 mm, thickness 4.1 mm. This protective lens offers a 99.5% light transmission rate, supporting efficient laser energy passage and stable cutting. Made from imported quartz crystal, it withstands high temperatures and corrosion, with a high laser damage threshold. Dual-sided anti-reflection coating minimizes reflection losses and resists debris buildup. Best for Raytools-compatible heads in high-precision, continuous operation. Caution: If your head uses a different lens diameter, this part may not fit without adapters.
CZlewan 10Pcs D28 Nozzle Set
Diameter 28 mm, caliber 1.6 mm. Premium purple copper construction delivers excellent heat resistance and thermal conductivity. The double-layer design enhances cutting efficiency for medium-thick plates, producing clean, burr-free surfaces. Chrome-plated precision with high concentricity ensures reliable alignment for carbon steel and other reactive materials. Best for high-speed cutting in high-temperature environments. Caution: Ensure thread M11 matches your machine’s nozzle mount.
Hgnova 5 Pcs Raytools Original Nozzle Set
Single-layer nozzle, 32 mm diameter with M14 thread and 2.0 mm caliber. Made from high-purity T2 copper for heat resistance and durability. Optimized for fast cutting speeds and high-quality finishes in fiber laser cutting heads. Best for high-speed operations with Raytools/WSX/Precitec/Boci heads. Caution: The single-layer design may offer less insulation than double-layer options in extreme heat scenarios.
Hgnova 4 Pcs Raytools Lens Set D30x5
Diameter 30 mm, thickness 5 mm. Features a 99.5% light transmission rate with high-temperature, corrosion-resistant quartz crystal material and a high laser damage threshold. Dual coating offers protection from reflections and debris. Best for Raytools/WSX/Precitec systems requiring larger lens surfaces. Caution: Check compatibility with your head’s optical module dimensions.
Buying Guide
What should I consider before buying protective lenses?
Key factors include diameter and thickness to match your head, material quality for thermal stability, and coating quality to minimize reflection. Larger lenses can handle higher energy but require compatible mounting.
Which nozzle type is best for my laser head?
Nozzle choice depends on required cutting speed, plate thickness, and material. Copper nozzles excel in heat management, while ceramic or alloy variants provide rigidity at high power. Ensure thread size matches your equipment.
Are these parts compatible with my specific laser head?
Compatibility varies by brand (Raytools, Precitec, WSX, Boci) and model. Always verify diameter, thread, and mounting standards before purchase. Some items are marketed as compatible with multiple brands but may require adapters.
How does coating affect performance?
Antireflection coating reduces wasted energy and debris buildup on optic surfaces. Dual-sided coatings provide better protection in harsh cutting environments and can extend optic life.
What is the best practice for installation?
Follow manufacturer installation guidelines, ensure clean mounting surfaces, and verify alignment after installation. Improper seating or misalignment can degrade cutting quality and shorten optic life.
What if I need a mix of lenses and nozzles?
Consider a combination kit that covers the most common diameters (27.9 mm, 30 mm) and nozzle calibers (1.6 mm, 2.0 mm). This approach reduces downtime when switching materials or projects.
FAQ
- Q: Do all protective lenses fit every Raytools head?
A: No, fit depends on diameter, thickness, and mounting style. Check product specs and your head model. - Q: Are these lenses and nozzles single-use?
A: Lenses are designed for long service life but may require replacement after damage. Nozzles may wear with use. - Q: Can I install these parts myself?
A: Basic maintenance and replacement can be DIY if you have the right tools and follow guidelines. Seek professional help if unsure. - Q: Will a higher-cost lens always improve performance?
A: Not always; ensure compatibility and correct coating for your application. Higher transmission helps, but other factors matter too. - Q: How can I extend optic life?
A: Maintain clean optical interfaces, avoid contamination, and replace damaged coatings promptly.
