Product 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.
