Precise and efficient homogenizing solution

A Micro Lens Array (MLA) contains multiple micro lenses in a square or hexagonal packing. Such arrays are often used for homogenization, beam shaping and coupling into fibers. Holo/Or’s MLAs are AR coated to handle high powered lasers, especially those used in medical and industrial applications.

Our advanced fabrication process allows us to offer you tailored high-resolution MLAs with SAG of up to 15um, including aspherization, conic constant control, and prism power, all according to your requirements. Our MLAs are offered with various packing-  cylindrical, square, rectangle and hexagonal.

For cost sensitive applications we offer polymer on glass (POG) MLA solutions with high durability to environmental conditions, suitable for low and mid-power laser applications.
