For optics processing, scia Systems offers several technologies and equipment, for example ion beam etching, ion beam deposition and magnetron sputtering. In this video, the focus of our Technical Sales Manager Philipp Böttger is on ion beam etching and how this technology can help you to structure your optics.
By introducing reactive gases into the etching process, called Reactive Ion Beam Etching, it is possible to control the selectivity of different surface materials or even to enhance the etch rate. This opens up different application possibilities, two of which are presented by Philipp Böttger:
The first is proportional or non-proportional pattern transfer from a resist mask using reactive ion beam etching. The second application example is the production of surface relief gratings which are used as input or output couplers in optical waveguides for augmented reality devices.
