Product Detail

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.
