Replicated Polymer microlenses on wafer
CSEM SA
CSEM is a privately held, R&D center established in 1984 in Neuchâtel, Switzerland. From the beginning, CSEM has been committed to both applied and order-related R&D. This bridge function between economics and science is still a core aspect of the company, and CSEM has continuously adapted its research areas to the needs of industry.
