High Precision Aspheric Lenses with AR Coating for Lasers - Top China Suppliers & Factory – 250-1600nm Wavelengths
●Product Description
Core Functions
- Aberration Correction: Aspheric curvature eliminates spherical aberration, field curvature, distortion for diffraction-limited performance (wavefront error <λ/4 RMS)1.
- High Transmission: AR coatings reduce reflection loss (<0.25% per surface), optimized for broadband (400–1100nm) or laser lines (355nm, 1064nm)12.
- Compact Design: Single aspheric lens replaces multi-spherical assemblies, cutting size/weight >50%1.
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 lasers12.
-
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)12.
-
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.
