Wafer level / micro-optics

For new and consistently improved products, such as mini-3D-cameras for mobile phone, beamers for smartphones and 3D screens, micro-optics are becoming more and more important. With newly developed, fast-curing and highly transparent imprint materials, DELO enables its customers to push forward these developments.

The lenses are produced by molding. Corresponding adhesives are also available for wafer bonding.
