Microlens array films manufactured by UV roll-to-roll imprinting

Top-of-the-line modern lithography machinery (direct write laser, DWL) has enabled significant performance and quality improvement on multilevel or continuous microstructures. One such microstructure is micro lens array, MLA. We can provide customizable, high quality MLAs according to your specfications.

Great tooling is accompanied with highly efficient production technology. UV roll-to-roll imprinting. This enables cost efficient and large volume production of MLA films. UV imprinting has very accurate replication of shapes that can’t be reached with traditional production technologies (IM, hot embossing).
