Precision Custom Cylindrical Lens Suppliers from China - High-Quality Factory Optics for Laser and Imaging Applications
Product Description
1. 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.
2. 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.
3. 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).
4. 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.
Differentiation Highlights
- Extended Depth of Focus: Toric lenses achieve ±50mm focal depth for large-DOF industrial inspection;
- High-Temperature Resistance: ZnSe withstands >300°C for semiconductor thermal processes.
