Citystar Smart Film: 87% Visible Light Transmittance Grade

Citystar smart film with 87% visible light transmittance is our best-selling premium grade, matching the highly popular hot-selling specification from Filmbase. This top-tier dimming film delivers outstanding optical performance, boasting an ultra-high visible light transmittance range of 87% to 89% under powered-on clear state, paired with an impressively low haze value between 3% and 4%. This low-haze formula is carefully developed to minimize the milky foggy tint that is common on ordinary PDLC smart film. When switched on, the film achieves glass-like clarity, allowing natural daylight to flow through without distortion or dull cloudiness, creating a clean, open visual effect that is highly sought after by high-end architectural projects around the world.

This grade distinguishes itself clearly from our cost-effective 85% transmittance variant. The tighter 3–4% haze rating is the core advantage here. For designers, contractors and end clients pursuing a premium, near-invisible look when the film is turned on, this specification is the ideal pick. Many luxury projects require the smart glass to look indistinguishable from standard clear glass in its powered state, and this Citystar smart film fulfills that requirement perfectly. Once power is cut off, it instantly switches into a uniform frosted opaque state for reliable privacy. The transition between clear and frosted is rapid, even across large panels, with consistent performance and no patchy switching, uneven clouding or dark edge defects that plague low-quality alternatives. Every panel goes through strict optical inspection before shipment to guarantee stable transmittance and haze data batch after batch.

Thanks to its superior optical performance, this 87% transmittance smart film is widely specified for high-end commercial interior applications. Modern office glass partitions are one of its largest application scenarios. Many high-grade office buildings hope to retain the openness and brightness of transparent glass for daily work communication, while still gaining instant privacy for confidential meetings. Installing this smart film removes the need for roller blinds, fabric curtains or fixed frosted patterns that ruin the minimalist aesthetic. Staff can toggle privacy on and off instantly with a simple wall switch, remote controller or smart home system.

Conference halls and high-end meeting rooms benefit greatly from this product as well. When there is no confidential discussion underway, the glass stays crystal clear to maintain an open layout and good natural lighting. Once private meetings start, the film switches to opaque mode in seconds. Besides privacy and partition functions, the evenly frosted surface in OFF mode works perfectly as a high-definition projection screen. It eliminates the extra cost and space occupied by a separate projection curtain, integrating partition, privacy and display all in one glass surface. This multi-functional characteristic makes it extremely popular among interior designers.

Museums and exhibition centers frequently select this low-haze smart film for dynamic exhibition design. Curators can keep the glass transparent to fully display artworks and exhibits to visitors, or switch it opaque to divide exhibition zones, create visual highlights, control sightlines and build immersive temporary display scenes. It brings flexible, changeable visual effects that static frosted glass cannot achieve.

Five-star hotels, luxury suites, high-end bars and boutique retail stores are also key markets for this premium smart film. For hotel shower enclosures and bathroom partitions, it maintains an elegant clean look when powered on and provides comfortable privacy when switched off. Upscale retail shopfronts can keep the glass transparent during business hours to showcase merchandise, then turn opaque after closing for security and decorative lighting effects.

Hospitals and medical clinics also adopt this specification for consultation rooms, ward dividers and nurse station glass. It protects patient privacy whenever required, while still allowing medical staff to observe wards conveniently when the film is transparent, balancing human-centered privacy protection and management efficiency.

All in all, this 87% transmittance Citystar smart film is our flagship popular model for high-end projects. It targets customers with strict requirements for high clarity and ultra-low haze. If your project demands premium optical performance and the clearest possible view in the ON state, this is the perfect option. It combines excellent appearance, reliable switching performance and multi-scene functionality, and has become the preferred PDLC dimming film for architects and glass processors worldwide.
