‌Precision Custom Cylindrical Lens for Optics

●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.
