    High Precision Optical Focusing Lens for Laser Applications


    1. Material Composition‌

    • ‌Lens substrate‌: Fused silica (SiO₂) or N-BK7 optical glass for high laser damage threshold (10-15 J/cm² @1064nm).
    • ‌Coatings‌: Multi-layer AR coatings (R<0.25% per surface) optimized for common laser wavelengths (e.g., 355nm, 532nm, 1064nm).
    • ‌Mounting‌: Anodized aluminum or titanium barrels for thermal stability.

    2. Key Properties‌

    • ‌Surface accuracy‌: λ/10 wavefront distortion for diffraction-limited performance.
    • ‌Focal length‌: 10-500mm with ±1% tolerance (telecentric options available).
    • ‌Aperture‌: f/1.4 to f/8 with <0.1% spherical aberration.
    • ‌Temperature range‌: -50°C to +300°C (coefficient matched to laser systems).


    ‌3. Core Functions‌

    • ‌Beam shaping‌: Converts Gaussian beams to flat-top profiles for uniform energy distribution.
    • ‌Spot size control‌: Achieves micron-scale focal spots (e.g., 5μm @532nm).
    • ‌Collimation‌: Corrects divergence in fiber-coupled laser systems.

    4. Applications‌

      • ‌Laser cutting/welding‌: Focuses high-power CO₂/YAG lasers (1-6kW).
      • ‌Medical lasers‌: Used in ophthalmology (LASIK) and dermatology devices.
      • ‌LIDAR systems‌: Optimizes signal-to-noise ratio in automotive/industrial scanners.
