High-Precision Meniscus Lenses from China Suppliers - Quality Optical Factory for Advanced Imaging Applications
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 & Customization
-
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.
-
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.
