Microlens Array – Precision Light Field Control and Beam Homogenization

Microlens Arrays (MLAs) consist of a large number of precisely arranged microlenses that split, shape, and homogenize light beams. They are essential in beam uniformization, light field imaging, laser systems, and sensors.

LUMINA manufactures various microlens arrays for advanced optical systems.Through ultra-precision molding, etching, and polishing, LUMINA delivers large-area arrays with high uniformity and consistency.

Optional AR and protective coatings are available, with strong capacity for scalable production.
