Boston University Photonics Center Annual Report 2019 the Above Image Is an Overview of MEMS Mirror Design
Boston University Photonics Center Annual Report 2019 The above image is an overview of MEMS mirror design. The image, featuring Professor David Bishop’s research, is a false color SEM image of the MEMS magnet mirror, comprised of four bimorphs that lift a polysilicon platform off the substrate. A 250 μm cubed N52 magnet is attached to the platform using a custom pick and place micro-gluing technique and a gold plated mirror is glued on top of the magnet using the same gluing technique.
