FLATLens® Control Rolls FLATLens® control rolls give OEMs developing linear LED fixtures a wide range of light management properties for continuous run applications up to 250ft FLATLens® innovations enable high-performance energy-efficient diffuse light in linear LED lighting applications. Particularly well suited to continuous run applications which demand no seams of several tens of metres. FLATLens® technology enables the encoding of a range of typical refractive, diffractive and scattering functions into optics that are both thin and flat. This innovative approach provides OEMs developing LED fixtures a wide range of light management properties and an additional after market revenue stream. FLATLens® control rolls are available in PMMA (acrylic) and PC (polycarbonate) and are typically between 0.5mm and 3mm thick.
