Asymmetric Light Diffusion Film (DFML)

How do you take a bright, annoying light source like an LED, and turn it into a work of art?

OptiGrafix™ Asymmetric Light Diffusion Films are specially engineered to shape bright point lights like LEDs. We manipulate the surface of our film to give you the ability to create unique, innovative lighting solutions.

By using this film at different angles and in different positions, you can create swirling lines of light in parallel, or in different directions. Pair this film with our Circular Light Diffusers to shape and blend the light to produce even backlighting effect.

Our Asymmetric Light Diffuser Film is commercially available at a price that will not break your budget when designing mass market light fixtures and signage. Applications include: Light fixtures, electronic signage, backlight systems, and other applications that require creative light play. This type of diffuser is useful for reducing the density of bright point sources, thus reducing component cost of the lighting system.
