High Resolution Wide-Angle Optical Lens for Action Cameras
1. Material Composition:
High-Index Optical Glass: Utilizes low-dispersion elements (e.g., ED glass) paired with aspheric components to minimize distortion and aberrations.
Multi-Layer Nano-Coating: Hydrophobic, anti-reflective, and abrasion-resistant coatings enhance light transmission and durability.
2. Key Properties:
Ultra-Wide Field of View: 120°–170° diagonal FoV for immersive capture without vignetting.
4K+ Resolution Support: Resolves >20 megapixels with minimal chromatic aberration and edge softness.
Low Distortion: Advanced optical design ensures <1% barrel distortion for realistic rendering.
Environmental Resistance: Waterproof (IP68), shockproof, and thermal stable (-20°C to 60°C).
3. Core Functions:
Immersive Capture: Expands field of view to include more scenery in extreme sports and adventures.
Edge-to-Edge Sharpness: Maintains focus clarity across the entire frame even at wide apertures.
Light Optimization: Maximizes light intake for superior low-light performance (e.g., f/2.0 aperture).
4. Applications:
Action Cameras: Compatible with GoPro, DJI Osmo, and Insta360 systems for sports filming.
Drone Imaging: Aerial photography and FPV racing lenses requiring wide FoV and stability.
Adventure Vlogging: Mountable on helmets, vehicles, or helmets for hands-free recording.
Underwater Videography: Corrosion-resistant housing for diving and snorkeling recordings.
