Microlens Array – Standard Stamp
NIL technology offers a wide range of standard microlens array, (MLA), standard stamps that can be used to emboss or injection mold micro lenses in to various polymer materials. The standard MLA stamps have been specifically designed for R&D work as well as for product and process development.
The stamps are offered in silicon and/or nickel. The lens diameters range from 1.3 µm to 20 µm with a SAG height ranging from 0.12 µm to 5.5 µm. The active areas on the standard MLA stamps ranges from 5 mm x 5 mm to 100 mm x 100 mm. The standard MLA stamps can be delivered with or without anti-sticking coating.
Note that the standard MLA stamps are only for test and product development purposes. A commercial use of the standard MLA stamp lens structures requires a royalty agreement.
