Anti-reflective Coating Optical Hemispherical Glass Dome for CCTV Photography

Material Composition
The dome is crafted from high-purity optical-grade glass (e.g., borosilicate or fused silica), renowned for its exceptional clarity and durability. It features a multi-layer anti-reflective (AR) coating, typically composed of thin-film materials like magnesium fluoride (MgF₂) or silicon dioxide (SiO₂), applied via vacuum deposition.

Key Properties

High Light Transmittance: The AR coating minimizes surface reflections (<1% reflectivity), ensuring ~99% light transmission for superior image clarity.

Scratch Resistance: Hardened glass and coatings resist abrasions, maintaining optical integrity in harsh environments.

Environmental Durability: UV-resistant coatings prevent yellowing, while hydrophobic layers repel water and dust.

Wide-Angle Performance: The hemispherical shape reduces geometric distortion, enabling seamless 180° field-of-view coverage.

Applications

Surveillance Systems: Deployed in public spaces (airports, streets), commercial buildings, and residential areas for unobstructed monitoring.

Traffic Monitoring: Enhances license plate recognition and incident detection under varying lighting conditions.

Industrial Security: Used in factories, warehouses, and offshore rigs to withstand corrosive or high-impact environments.

Smart Cities: Supports AI-powered analytics by delivering distortion-free footage for facial recognition or motion tracking.

Functional Benefits

Glare Reduction: Eliminates unwanted reflections from ambient light (e.g., headlights, sunlight), critical for 24/7 CCTV surveillance.

Weatherproofing: Protects internal camera lenses from rain, dirt, and vandalism.

Color Accuracy: Preserves true-to-life color reproduction by minimizing spectral distortion.
