Description

Opto Films are precision-engineered optical polymer films designed to control, enhance, and manage light within advanced LED lighting, display, and backlighting systems. By selectively diffusing, reflecting, or blocking light, these films enable manufacturers and lighting designers to achieve uniform illumination, high system efficiency, and controlled visual output in compact and ultra-thin designs.

At Hexatron Technologies, our Opto Films are developed to integrate seamlessly with Light Guide Plates (LGPs), diffuser sheets, and LED modules. They form a critical layer in the “optical stack”, ensuring that every lumen is directed precisely where it is needed. Available in both PET and Polycarbonate (PC) materials, our films offer a versatile range of thicknesses (100–500 ΞΌm) and surface finishes to meet the most demanding optical specifications.

Diffuser Films: Smoothing and Uniformity

Diffuser Films are engineered to eliminate “hot spots” and smooth out luminance variations across a surface. By scattering light at the microscopic level, these films improve visual comfort and ensure a perfectly uniform glow, even in ultra-thin LED panels where the light source is close to the viewing surface. They are essential for high-brightness displays and architectural fixtures where a “seamless” light appearance is required.

Reflector Films: Maximizing System Efficiency

Reflector Films are high-reflectivity layers placed at the back of the optical stack. Their primary function is to redirect backward-emitted light toward the intended illumination surface. By minimizing light loss within the fixture, our reflector films significantly increase the overall Luminous Efficacy of the system. We offer both PET and PC-based white reflector films, allowing designers to choose the best balance of thermal stability and reflectivity for their specific application.

Light-Blocking Films: Precision and Contrast

Light-Blocking Films (also known as masking films) are opaque or low-transmission films used to define illumination zones and prevent unwanted light leakage. These films are critical for improving contrast in displays and ensuring “clean” edges in architectural linear lighting. By effectively containing light within designated paths, they allow for high-precision optical designs and prevent “ghosting” or light bleed in multi-zone lighting systems.
