As a leading glass manufacturer, MIGO GLASS provides professional insights into three mainstream optical glass surface treatment technologies.
-
AG Glass (Anti-Glare Glass)
AG glass utilizes chemical etching or mechanical processing to create micron-level rough structures on the glass surface. This specialized surface treatment technology effectively reduces glare caused by ambient light reflection through light scattering principles. The surface roughness is typically controlled within the range of 0.1-0.3μm, ensuring optimal anti-glare performance without significantly compromising light transmittance.
-
AR Glass (Anti-Reflective Glass)
AR glass employs vacuum coating technology to deposit multiple optical thin film layers (e.g., SiO₂, TiO₂) on the surface. These films are precisely designed with specific refractive indices to eliminate over 99% of surface reflections through light wave interference. Our coating technology achieves an average reflectivity of less than 0.5% across the visible light spectrum, significantly enhancing light transmission and display clarity.
-
AF Glass (Anti-Fingerprint Glass)
AF glass incorporates advanced nano-coating technology to form an ultra-thin (approximately 5-20nm) hydrophobic and oleophobic layer on the surface. This coating reduces surface energy (contact angle >110°), preventing fingerprint oils and water stains from adhering. A simple wipe is sufficient to maintain surface cleanliness. We utilize Plasma-Enhanced Chemical Vapor Deposition (PECVD) technology to ensure coating uniformity and durability.
Key Properties Comparison
| AG Glass | AR Glass | AF Glass | |
|---|---|---|---|
| Glare Reduction | ✔ Excellent (matte finish) | ✔ Good (clear but low reflection) | ✘ Minimal effect |
| Reflection Control | Moderate (light diffusion) | ✔ Best (near-invisible reflections) | ✘ No impact |
| Fingerprint Resistance | ✔ Good (matte hides smudges) | ✘ Poor (shows smudges) | ✔ Excellent (oil-repellent) |
| Light Transmission | ~85-90% | Up to 98% | Depends on the base glass |
| Durability | High (etched surface) | Moderate (coatings can wear) | Moderate (coating degrades over time) |
| Maintenance | Easy to clean | Requires gentle cleaning | ✔ Very easy (smudges wipe off easily) |
Technologies Combination
MIGO GLASS offers hybrid solutions for superior performance:
- AG + AR Glass → Reduces glare and reflections (ideal for high-end displays)
- AR + AF Glass → Ultra-clear and fingerprint-resistant (perfect for touchscreens)
- AG + AF Glass → Matte finish with easy cleaning (great for public kiosks)
