‌Precision Aspheric Lens for Laser/Optical Systems with AR Coating

●Product Description

1.‌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.
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 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.
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.
