SwissOptic AG has announced a coating process that can be applied to optical interference filters. The application can be repeated to define multiple areas of different filters on one substrate surface. Possible filters include color long-, short- and bandpass types. The feature size is dependent on the thickness of the coating; the minimum achievable is 2 µm. Spectral characteristics of the filters can be customized for specific applications, including optics, cameras and sensors.
