Precision Custom Cylindrical Lenses from China Suppliers and Factory | Single-Axis Curvature for Optics

Discover ALHAZEN's custom cylindrical lenses, expertly crafted in our factory to meet high-performance standards. Featuring a single-axis curvature design (plano-convex, plano-concave, and toric), our lenses achieve exceptional surface flatness of <λ/5 (@633nm) and maintain a precise diameter tolerance of ±0.02mm. These lenses are compatible with wavelengths ranging from 200nm to 14µm, making them ideal for applications in laser beam shaping, semiconductor inspection, and medical imaging. As a leading supplier in China, we are committed to delivering quality optical solutions that meet the specific needs of our clients.

Product Detail

Product Description

Core Functions

Single-Axis Focus/Divergence: Converts laser beams to line spots (1:100 aspect ratio) or corrects astigmatism;
Beam Shaping: Collimates elliptical beams to circular (<5% ellipticity) for uniform laser processing.
Broadband Compatibility: Materials include UV fused silica, N-BK7, ZnSe for DUV to LWIR.

Technical Specifications

Materials & Design:
- UV Fused Silica: >90% transmission @200–2500nm, high LIDT (>10J/cm² @355nm);
- IR Materials (Ge, ZnSe): Covers 3–14μm for CO₂ lasers (10.6μm).
Precision:
- Surface flatness <λ/5 (@633nm), radius tolerance ±0.5%;
- Diameter 5–300mm, thickness tolerance ±0.05mm, eccentricity ≤1 arcmin;
- Surface quality 40-20 scratch/dig (upgradable to 10-5).
Coatings:
- AR Coatings: <0.5% reflectivity per surface (e.g., 355nm, 1064nm);
- BBAR Coatings: 400–1200nm range with <0.8% average reflectivity;
- Metallic Coatings (Al, Au): For IR reflection or harsh environments.

Applications

Laser Processing: Line focusing in fiber laser cutting for metal processing;
Semiconductor Inspection: Beam homogenization in wafer defect detection (±1μm resolution);
Medical Imaging: Astigmatism correction in OCT systems (<5μm axial resolution).

Customization

Complex Profiles: Toric, aspheric cylindrical lenses, or doublet/triplet assemblies;
Custom Shapes: Rectangular/arc-cut designs with tailored edges or holes;
Fast Turnaround: Standard orders in 5 days, special requests <3 weeks.
