Messe

SPIE Photonics West is the leading event on the US west coast for lasers, photonics and biomedical optics. It covers a wide range of topics: Industrial lasers, optoelectronics, micro manufacturing, MOEMS-MEMS, displays and more.

Find the latest components, devices and systems for your research or business needs. The Fraunhofer IPMS will be present at booth 4361 to present our latest developments.

At the SPIE Photonics West, the world's leading trade show and conference for lasers, photonics and biomedical optics in San Francisco from February 1-6, 2020, visitors can inform themselves about the latest developments of Fraunhofer IPMS. The Fraunhofer IPMS booth will be located in the North Hall at booth #4361 from Feb. 4-6, 2020. On Feb. 1 and 5, 2020 our scientists will give lectures on the latest Fraunhofer IPMS technologies during the SPIE Conference.

Electrostatically driven micro bending actuators

This allows large vertical or lateral deflections with low energy consumption and low electrical drive voltage. The technology is suitable for extending existing microsystem solutions and for opening up new areas of application with novel designs. Application areas range from positioning drives for miniaturized optical zoom lens systems to micropumps, microvalves and even the smallest speakers for hearing aids and hearables.

MEMS scanner mirror

Resonant or quasi-static operation for targeted light deflection with very compact systems. The range of applications extends from bar code reading systems and 3D metrology to laser projection, spectroscopy and focus position modulation. With the Resolin evaluation kit "QSDrive Scan Kit", Fraunhofer IPMS offers the possibility to test cost-saving and flexible statically deflectable MEMS scanner mirrors for applications that could not be operated satisfactorily with the common resonant oscillating microscanners so far.

Liquid crystal switch / adjustable power divider

Optical switches based on the principle of electro-optically induced waveguides in thermotropic liquid crystals in the isotropic phase The underlying Kerr effect in these liquid crystals makes fast switching possible. The components can be used e.g. in optical telecommunications or for fiber optic sensor technologies.

Area light modulators (MEMS mirror arrays)

MEMS mirror arrays on a semiconductor chip with up to several million individual mirrors. Depending on the application, these can be tilted or lowered individually to create a flat pattern that can be used to project defined structures, for example. High-resolution tilted mirror arrays with up to 2.2 million individual mirrors are used by our customers as highly dynamic programmable masks for optical microlithography in the ultraviolet range. Mirror dimensions here are 10 μm or larger. By deflecting the micromirrors, the structure information is transferred into the photoresist at a high frame rate. Further fields of application are semiconductor inspection and measurement technology, microscopy, spectroscopy, laser marking, labelling and material processing.
