Focal plane filter mosaics for optical application
To fabricate mosaic filters with spectral characteristics it is required to arrange the different spectral areas laterally with an accuracy of a few pixels. Similarly all of the adjacent subfilters must be arranged without any gap, requiring a micrometer (µm) accuracy of the lateral edges.
This can only be realised by a sophisticated lithography which was developed by Supracon.
