Lens-on-MEMS Technology Could Lead to More Compact Optical Devices

Facebook Twitter LinkedIn Email Comments
In a collaboration between Argonne National Laboratory and Harvard University, researchers have built a metasurface-based lens on top of a MEMS platform, creating a “lens-on-MEMS” device that focuses light in the MIR spectrum. The MEMS-integrated metasurface lens combines the best features of both technologies while reducing the size of the optical system. It measures 900 m in diameter and is 10 m thick. In this hybrid device, MEMS mirrors reflect scanned light, which the metalens then focuses without the need for an additional optical component, such as a focusing lens. A...Read full article
