Description

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.
