Polymer damper



In close cooperation with GMT, a polymer damper with an extremely high damping ratio of 50% has been developed and is currently produced in volume.

To apply damping to the suspension of an optical module used in next generation lithography tools, a dedicated polymer damper has been developed. To reach the extremely high damping values, a new polymer material was developed in close cooperation with GMT. The dampers are produced in volume and their performance has been verified. MI-Partners has developed in-depth knowledge regarding the design of polymer dampers. Models have been developed such that these dampers can be developed and produced with a first-time-right strategy in future projects. See the Video.
