Microlens Arrays - Free Form Lenses with Highest Precision

In addition to standardized-micro optics LIMO offers customized microlens arrays. By the use of LIMO's technology we manufacture free form lenses with highest precision on variable wafer sizes (up to 350 mm).

LIMO's technology allows the processing of a large range of materials, such as:

  • Optical glass: fused silica, BK7, S-TIH53
  • Crystals: CaF2, YAG, LuAG
  • Semiconductors: Si, Ge, ZnSe
  • Ceramics
Effective focal length [mm]Pitch [mm]Size [mm²]
4.23 - 61.60.512x12
8.55 - 206.50.820x20
5.88 - 98.31.335x35

LIMO also offers double-sided structured microlens arrays which can be used for uniform laser illumination. Please find more information on our homogenizers here.
