A technical guide to optical diffuser films for LED lighting — covering PET vs PC substrates, transmittance grades, haze, how films fit within an optical stack, and applications across commercial, display, and architectural lighting.
A technical guide to injection molded light guide plates — covering the manufacturing process, mold design, PC vs PMMA material selection, dot pattern integration, and when injection molding is the right production route for your LGP application.
A complete technical comparison of PMMA, polycarbonate (PC), and polystyrene (PS) for LED diffusers and optical sheets. Covers optical transmittance, impact resistance, fire ratings, UV stability, thermal behaviour, and application-by-application guidance to help engineers and buyers specify the right material first time.
In lighting design, materials need to do more than just look good — they must perform, adapt, and last. At Hexatron, we’ve worked with optical-grade materials for years, and when it comes to thermoformed diffusers, one material stands out: PMMA (Polymethyl Methacrylate). Why PMMA Is Ideal for Thermoforming PMMA, also known as acrylic, offers several advantages that make it […]
In critical environments like hospitals, laboratories, and cleanrooms, lighting plays an essential role not only in visibility and aesthetics but also in hygiene, safety, and human well-being. In such places, every component of the lighting system—from the housing to the diffuser—must meet strict standards for durability, optical quality, and chemical resistance. One of the most […]
How optical diffuser films and prismatic sheets combine to achieve UGR<19 in LED panels. Covers prism profiles (Honeycomb, Hexagon, Pyramid), diffuser film grades, assembly methods, and optical stack design for commercial lighting.
Creating visually comfortable indoor environments requires lighting systems that minimize glare while maintaining high efficiency. One of the most effective approaches is the combination of micro prismatic sheets and optical diffuser films, commonly used in LED luminaires designed to achieve a Unified Glare Rating (UGR) below 19, the recommended limit for office and indoor lighting according to EN12464 lighting standards.
