Optical Film

Metal-free optical film with chrome-like appearance and radar transparency.
Perfect for RADAR, LIDAR, and HUD applications in modern vehicles.

Decorative Optical Film for Sensor Integration Without Signal Interference

NAGASE’s Optical Film is a high-performance, formable, metal-free decorative film that mimics the appearance of metallic materials while ensuring full compatibility with automotive sensor technologies. Unlike real metal coatings, this advanced polymer-based film allows for excellent radar and infrared wave transmission, making it the optimal choice for sensor housings in next-generation vehicles.

Its nano-multilayer construction provides a brilliant chrome or metallic finish without compromising signal clarity. Available in variants for infrared (IR) reflection or transmission, Optical Film ensures seamless integration into parts like RADAR covers, LIDAR sensors, and HUD displays – without risk of interference or distortion.

NAGASE supplies Optical Film globally for automotive OEMs and Tier 1 suppliers, delivering functional surface materials tailored to tomorrow’s mobility challenges.

Frequently Asked Questions about Optical Film

What is Optical Film used for in automotive applications?
It is mainly used for sensor covers and display components that require metallic appearance without blocking radar or IR signals.

Why is it important that the film is metal-free?
Metal particles can distort or block signals in RADAR and LIDAR systems. Being metal-free ensures high signal clarity and system performance.

Can this film be thermoformed for complex shapes?
Yes, the film is fully formable and suited for 3D contouring in exterior parts and sensor housings.

Is the chrome effect real metal?
No, it’s a visual effect achieved through nano-layer polymer structures – offering a similar look without the drawbacks of real metal.

Are there different versions of Optical Film?
Yes, NAGASE offers versions with IR reflection or IR transmission depending on application needs.
