Precision Aspheric Lenses with AR Coating for Laser Systems - China Suppliers | High-Quality Factory Manufacturing
●Product Description
1. 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%.
2. 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.
3. 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.
4. 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.
