From smartphone cameras to Mars rovers, optical coatings are the unsung heroes of light management. This guide breaks down coating types, applications, and Guiyu’s Japan Guangchi-powered solutions.
1. Coating Types & Applications
| Type | Function | Use Case |
|---|---|---|
| Anti-Reflective (AR) | Reduces reflectivity to <0.5% | Camera lenses, displays |
| IR Cut-Off | Blocks 700-1200nm wavelengths | Thermal imaging systems |
| Dichroic | Splits light by wavelength | Medical lasers |
2. The Coating Process
- Deposition: Electron-beam evaporation at 10⁻⁶ Torr vacuum.
- Monitoring: Real-time spectral analysis via Hitachi UH4150.
- Durability Testing: 500+ hours salt spray (ASTM B117).
3. Emerging Innovations
- Photonic Crystals: Self-cleaning coatings for outdoor optics.
- Metamaterials: Negative-index coatings for military stealth tech.
