How Our AR Stack Works on PC

A precisely engineered sequence of optical thin films, each serving a distinct role in eliminating reflection while preserving the mechanical integrity of the polycarbonate substrate.

Customizable Wavelength Range

Standard broadband (400-700nm) or application-specific: NIR-enhanced (700-1100nm) for sensor windows, UV-extended for inspection systems. Specify your target wavelength in the RFQ.

The PC-AR Coating Challenge

Polycarbonate's low surface energy and thermal sensitivity make standard glass AR processes fail. Winson's process is engineered from the substrate up.

Thermal Sensitivity

PC distorts above 120°C -- our low-temperature PECVD deposition stays under 80°C throughout.

Adhesion Failure

Inorganic coatings peel on bare PC. Our proprietary hard-coat primer ensures >3B adhesion per ASTM D3359.

Durability Trade-off

Thin coatings scratch easily; thick ones crack. Our graded-index stack balances hardness (3H pencil) with flexibility.

Technical FAQ

Questions R&D Engineers Ask

Straight answers to the technical questions that matter most when specifying AR-coated PC components.

Can standard vacuum-deposited AR coatings be applied directly to PC without a primer?

No. Bare PC has low surface energy and the thermal expansion mismatch between inorganic coating materials (SiO₂, TiO₂) and PC is significant. Without a hard-coat primer, adhesion will fail within 50-100 thermal cycles. Our SiC-based primer bridges this mismatch and provides a stable, chemically bonded interface for the optical stack. This is the most common failure mode we see in competitor samples.

What is the maximum operating temperature for AR-coated PC windows?

Continuous operating temperature is limited by the PC substrate: typically -40°C to +110°C for standard grades, up to +130°C for high-heat PC grades. The coating itself is stable to over 200°C, but the substrate will deform first. For applications above 110°C, we recommend switching to our sapphire or borosilicate glass AR windows instead.

Can you coat only one side and leave the other side uncoated or with a different treatment?

Yes. We support single-side AR with the reverse side having: bare PC, hard-coat only, anti-fingerprint (AF) coating, or even a custom silk-screened border/logo. Mixed coating configurations are handled in our multi-step process and are priced accordingly. Specify your requirements in the RFQ form and our engineers will confirm feasibility within 24 hours.

How does the AR coating affect touchscreen performance (capacitive sensing)?

Our standard AR stack uses non-conductive dielectric materials (SiO₂, TiO₂, MgF₂) and does not affect capacitive sensing. The total coating thickness is typically 0.3-0.8μm -- negligible compared to the PC substrate thickness. For applications requiring precise capacitive tuning, we can provide dielectric constant measurements of the coated stack. ITO-compatible versions are also available for resistive touch applications.

What is the minimum order for prototypes, and what documentation is provided?

Prototype MOQ is 5 pieces with a lead time of 7-10 business days. Each prototype order includes: dimensional inspection report, spectral transmission curve (witness sample), cross-hatch adhesion test result, and a Certificate of Conformance. We can also provide a material data sheet for the specific PC grade used. Prototype pricing is quoted separately from production pricing.

Can the AR coating be combined with other functional coatings (EMI shielding, anti-fog)?

Yes, with caveats. AR + anti-fingerprint (AF) is our most common combination and is standard. AR + ITO (for EMI/touch) requires careful stack design to avoid optical interference -- feasible but adds 2-3 weeks to development. AR + anti-fog hydrophilic coatings are possible for outdoor enclosures. Each functional combination requires separate optical design and validation. Describe your requirements in the inquiry and we'll advise on the most practical stack.
