Customized
AR / AG / AF
Coated Glass
Engineered for precision instruments, medical devices, and industrial displays. Multi-layer PVD/CVD coating technology delivering <0.3% reflectance, 4H pencil hardness, and contact angle >110° -- fully customized to your optical specifications.
Three Coating Types, One Supplier
Whether you need a single-function coating or a hybrid stack, our PVD/CVD deposition process delivers consistent, repeatable results at production scale.
Anti-Reflective (AR)
Multi-layer MgF₂ / SiO₂ / TiO₂ stack eliminates surface glare and maximizes light transmission. Critical for optical instruments, HUD systems, and medical imaging where signal clarity is non-negotiable.
- Reflectance < 0.3% per surface
- Transmission > 99.5%
- Wavelength range: 400-1100 nm
- Single or dual-side coating
Anti-Glare (AG)
Controlled micro-etching or nano-coating diffuses specular reflections without sacrificing clarity. Ideal for touch panels, industrial HMIs, and outdoor displays operating under direct ambient light.
- Haze level: 2%-25% (tunable)
- Gloss: 60-130 GU (customizable)
- Chemical etch or PVD process
- Pencil hardness ≥ 3H
Anti-Fingerprint (AF)
Fluoropolymer nano-coating creates a low surface energy barrier (>110° water contact angle) that repels oils, fingerprints, and contaminants. Maintains optical clarity under repeated touch cycles in high-use environments.
- Contact angle > 110°
- Pencil hardness: 4H
- Abrasion: >5,000 wipe cycles
- Vacuum evaporation deposition
Hybrid Coating Stacks: AR + AG + AF in One Part
Need multiple properties on a single substrate? We engineer multi-functional coating stacks -- e.g., AR on the inner surface + AG+AF on the outer surface -- with full spectral and durability validation. Common in medical displays and precision instrument covers.

From Drawing to Delivery
A transparent, auditable workflow -- designed by someone who spent 12 years on the buying side. No surprises, no hidden steps.
Submit Specs
Share your drawings, material requirements, coating specs, and quantity targets. DXF, PDF, or even a sketch -- we work with what you have.
Engineering Review
Our optical engineers assess DFM feasibility, propose coating stack options, and confirm tolerances. Written technical response within 24 hours.
Prototype & Validate
First-article samples with full CoC: spectral curves, contact angle data, and dimensional report. Typically 7-14 business days for standard substrates.
Mass Production
100% inspection before shipment. Batch CoC, packing list, and traceability documentation included. Export packaging for USA/EU logistics standards.
Managed with a Procurement Mindset
Iris, our co-founder, spent 12 years as a professional buyer before joining Winson in 2025. She knows exactly what purchasing managers in Germany, the UK, and the USA need: complete documentation, predictable lead times, and zero ambiguity in the CoC.
That's why every AR/AG/AF order ships with a full traceability package -- substrate batch records, coating run data, spectral measurement reports, and dimensional inspection sheets -- ready for your incoming QC.
