Anti-Reflective Coated Glass Disc for Camera Protector and Sensor Windows
1. Material Composition:
Optical-Grade Glass: High-purity borosilicate or aluminosilicate glass with exceptional surface flatness and homogeneity.
Multi-Layer AR Coating: Nano-scale anti-reflective coatings deposited via ion beam sputtering for maximum light transmission.
2. Key Properties:
Ultra-High Transmission: Achieves >98% light transmission across visible and NIR spectra (400-1100nm) with minimal reflectance (<0.5%).
Scratch Resistance: Hardness of 9H (pencil test) and abrasion resistance for long-term durability.
Environmental Stability: Withstands temperature cycles (-30°C to 150°C) and humidity (85% RH) without coating degradation.
Chemical Inertness: Resists acids, solvents, and oils for easy cleaning in industrial environments.
3. Core Functions:
Glare Elimination: Suppresses reflections to enhance image contrast and accuracy in imaging systems.
Physical Protection: Shields sensitive camera sensors and optical components from dust, moisture, and mechanical damage.
Optical Neutrality: Preserves color fidelity and prevents vignetting in high-precision imaging applications.
4. Applications:
Camera Protectors: Front covers for smartphone lenses, DSLR cameras, and security surveillance systems.
Sensor Windows: Protective barriers for CMOS/CCD sensors, LiDAR systems, and thermal imaging devices.
Industrial Imaging: Inspection machines, barcode scanners, and automated optical alignment systems.
Medical Devices: Endoscope lenses, diagnostic sensor windows, and laboratory instrument optics.
