Microlenses for Anticounterfeit applications

Refractive microlenses cover a range  of 10 µm to 2 mm lens diameters  Refractive microlenses are an  interesting alternative for all applications where miniaturization and reduction of alignment and packaging costs are necessary. A refractive microlens refracts the incident light according to Snell's law, similar as large-scale glass lenses do. Refractive microlenses are manufactured in Fused Silica or Silicon or plastic materials, the  later case being interesting for anticounterfeit techniques.  We have realized the master for high productivity moulding of microlens arrays, targeting drug industry, with  sizes down to 30 microns diameter.
