Micro lens arrays (MLAs) consist of microscale lenses used to manage and shape light in various applications, including consumer and automotive displays, LiDAR, sensing systems, and LED lighting.
MLAs can take on a variety of shapes and sizes to suit the required light output based on a given light input. They can also be custom-made for a particular application or device. They are created using a grayscale lithography technique to individually "write" patterns into a specially formulated photosensitive resist, as opposed to conventional diffuser films that rely on light scattering. These patterns are converted into products using a high-capacity, roll-to-roll production.
Micro lens arrays are an attractive solution in applications where a cost-effective and efficient light management solution is needed.
