Anti-Reflection (AR) Coating
Multi-layer AR coatings that drive light transmission to 99%+, eliminating reflections that compromise critical optical performance.
The Physics of
Interference
Standard glass loses ~8% of light to reflection. Winson solves this at the molecular level through multi-layer nano-stacking.
Nano-Stack Engineering
We deposit alternating layers of Magnesium Fluoride and Metal Oxides. By controlling thickness to ±1nm, we create phase-shifted waves that cancel reflections across the full visible spectrum.
High-Energy Sputtering
Unlike "soft" evaporation coatings, our vacuum sputtering ensures atomic-level adhesion. The film becomes part of the substrate, preventing peeling under thermal cycling and humidity stress.
Eliminate Optical Interference
Same substrate. Same lighting. The difference is the coating stack.
Ion-assisted sputtering · 7-layer nano-stack · ±1nm thickness control
Coating Solutions by Application
We calibrate the optical stack based on your specific wavelength and durability requirements.

Why Purchasing Managers Choose Winson AR
"In the optics trade, a coating is only as good as its adhesion. Cheap evaporation AR often fails environmental tests within months. As your sourcing ally, I ensure our vacuum chambers utilize Ion-Assisted Sputtering. We don't just provide clarity; we provide industrial-grade durability that protects your brand's reputation."
