Precision Aspheric Lens with AR Coating for Laser/Optical Systems - China Suppliers Factory

ALHAZEN's precision aspheric lenses are engineered to eliminate spherical and astigmatic aberrations through an innovative asymmetric curvature design. With an impressive surface accuracy of ±0.1μm and greater than 99.5% AR coating transmission, these lenses are compatible with a wide range of wavelengths from 250 to 1600nm. They are perfect for applications in laser focusing, high-resolution imaging, and compact optoelectronics. As a trusted supplier with a state-of-the-art factory in China, we ensure top-quality products that meet the highest industry standards.

    Product Description

    Core Functions

    • Aberration Correction: Aspheric curvature eliminates spherical aberration, field curvature, distortion for diffraction-limited performance (wavefront error <λ/4 RMS).
    • High Transmission: AR coatings reduce reflection loss (<0.25% per surface), optimized for broadband (400–1100nm) or laser lines (355nm, 1064nm).
    • Compact Design: Single aspheric lens replaces multi-spherical assemblies, cutting size/weight >50%.

    Technical Specifications

    • Materials & Processes:
      • Moulded Glass: Surface accuracy ±0.5μm for VIS-NIR;
      • Diamond-Turned: IR materials (ZnSe, Ge) with roughness <10nm Ra;
      • UV Fused Silica: High LIDT (>5J/cm² @355nm) for UV lasers.
    • Precision:
      • Surface figure <0.1μm PV, slope error <0.5μm/mm;
      • Center thickness tolerance ±0.02mm, diameter ±0.05mm, clear aperture >90%;
      • Surface quality 20-10 scratch/dig (optional 10-5 ultra-precision).
    • Coatings:
      • Broadband AR: Average reflectivity <0.5% (400–1100nm);
      • High-LIDT AR: Compatible with >10kW/cm² CW or femtosecond lasers.

    Applications

    • Laser Processing: Focus lenses for fiber laser cutting heads, enhancing beam quality;
    • Imaging Systems: Compact lens arrays in endoscopes/microscopes for aberration-free imaging;
    • Optical Communication: Collimation lenses in FSO modules, minimizing coupling loss.

    Customization

    • Complex Profiles: Double aspheric, diffractive hybrid, or freeform surfaces;
    • Pre-Aligned Modules: Integrated with collimators/isolators for plug-and-play assembly;
    • Fast Turnaround: Standard orders in 7 days, special requests <4 weeks.

    Differentiation Highlights

    • Nanoscale Surface Control: Interferometer/profilometer dual QC ensures λ/10 wavefront accuracy for EUV lithography or telescopes;
    • Multi-Process Versatility: Diamond-turned aspherics cover 3–20μm IR for thermal imaging or gas sensing.
