High-Precision Meniscus Lens for Advanced Optical Systems

●Product Description

1.‌Core Functions‌
●Positive Meniscus Lens‌:
·Larger convex curvature, smaller concave curvature for focal lengths ‌2.5–10‌, reduces spot size and enhances focusing (e.g., high-power lasers or microscope objectives)‌.
●Negative Meniscus Lens‌:
●Larger concave curvature, compatible with IR materials (‌Ge, ZnSe‌), minimizes spherical aberration in beam expansion for fiber coupling or wide-FOV imaging‌.
2.‌Technical Specifications‌
●Materials‌:
·H-K9L Glass‌: High transmission in visible range (400–700nm), cost-effective;
·Fused Silica‌: UV-NIR (190nm–2.1μm) compatibility, thermal and laser damage resistance‌.
●Precision‌:
·Surface flatness ‌λ/5‌ (@633nm), eccentricity ‌≤1 arcmin‌, focal length tolerance ‌<±1%‌;
·Diameter tolerance ‌+0.00/-0.02mm‌, thickness ‌±0.05mm‌, scratch/dig ‌40/20‌ (upgradable to ‌20/10‌)‌.
●Coatings‌:
·Anti-Reflective (AR)‌: Single/dual-sided for 355nm–2μm wavelengths;
·High-LIDT Coatings‌: Compatible with ‌CO₂ lasers (10.6μm)‌ or femtosecond systems‌.
3.‌Applications‌
●Laser Processing‌: Focus laser beams to micron-level spots using positive meniscus lenses;
●Infrared Imaging‌: Negative meniscus lenses with Ge substrates expand thermal camera FOV;
●Optical Correction‌: Combine with plano-convex/concave lenses to compensate aberrations‌.
4.‌Customization‌
●Aspheric Design‌: Reduces spherical aberration for uniform beam profiles;
●Special Dimensions‌: Diameter ‌2–200mm‌, radius of curvature ‌10–1000mm‌, asymmetric shaping;
●Fast Turnaround‌: Standard orders in ‌7 days‌, IR materials ‌<4 weeks‌‌.

●Differentiation Highlights

●Ultra-Low Eccentricity‌: Precision alignment ensures ‌≤30 arcsec‌ deviation between optical/mechanical axes for interferometers;
●Broad Temperature Stability‌: Fused silica variants operate in ‌-50°C to 300°C‌ for aerospace optics‌.
