IREEDA Industrial Laser Lens | K9/Quartz Material | AR Coating R<0.1% @ 1064nm/532nm | Plano-Convex/Spherical Optical Components
Key Feactures
1. Ultra-Low Reflectivity & Maximum Efficiency
Engineered with advanced IAD (Ion-Assisted Deposition) electron beam evaporation, our lenses feature a high-performance multi-band AR coating. With reflectivity R<0.1% at 1064nm, 532nm, and 650nm, it minimizes energy loss and safeguards your laser source from harmful back-reflections.
IREEDA offer two high-grade material options: K9 (BK7) for cost-effective visible to NIR applications, and Synthetic Fused Silica (Quartz) for high-power laser systems. Fused Silica provides an exceptionally low thermal expansion coefficient and superior UV-to-IR transparency.
3. High Laser Damage Threshold (LDT)
Specifically designed for industrial-strength laser processing, these lenses can withstand high-peak-power pulsed lasers. They are the ideal choice for high-intensity applications such as laser marking, precision cutting, welding, and internal resonator optics.
4. Exceptional Surface Accuracy & Clarity
Each lens is polished to a superior surface flatness of <λ/4 and a surface quality of 20/10 Scratch-Dig. This ensures minimal wavefront distortion and high-fidelity focus/collimation, crucial for high-precision laser machining.
5. Comprehensive Customization (OEM/ODM)
Beyond standard ϕ15/20mm sizes, we provide end-to-end customization. Whether you require specific diameters, focal lengths (F), center thicknesses, or complex geometries (Plano-Convex, Meniscus, or Spherical), our engineering team can deliver tailor-made solutions for your unique optical designs.

FAQ
Q1: How do I choose between K9 (BK7) and Fused Silica (Quartz) for my application?
A: K9 (BK7) is ideal for standard visible and near-infrared laser applications where cost-effectiveness is a priority. For high-power laser systems (e.g., laser cutting/welding) or UV applications, we recommend Fused Silica (Quartz) due to its significantly higher laser damage threshold and superior thermal stability, which prevents focus shift.
Q2: Can you provide customized specifications beyond the standard range?
A: Yes, we offer full OEM/ODM services. We can customize diameters (from ϕ2mm to ϕ100mm), specific focal lengths, and center thicknesses. We can also optimize the AR coating for other specific wavelengths (e.g., 355nm, 808nm, or 1550nm) to meet your unique optical design requirements.
Q3: What are the advantages of your R < 0.1% multi-band AR coating?
A: Our premium coating ensures maximum energy transmission and near-zero back-reflections. This is crucial for:
- Protecting your laser source from harmful feedback reflections.
- Reducing thermal lensing effects, ensuring the laser spot remains stable during long-term operation.
- Improving the overall efficiency and precision of your laser processing system.
