Pixel Level Mosaic Filters or Mosaic filters are a kind of sophisticated multispectral filters with intensive integration of spectral and photometric functions. Pixel level mosaic filter is fabricated by organizing multiple micrometer-scale spectral channels into spectral periods that follow the RGB color filter arrangement. These spectral periods then form a mosaic pattern across the surface of the filter. A pixel level mosaic filter divides the entire field of view of the sensor or imaging system into numerous miniature areas and assigns different constituent spectral channels of the filters to each of these areas. This allows simultaneous and efficient processing of information from multiple spectral ranges. Furthermore, the rich and delicate division of the spectral channel areas permits precise and potent control over the optical characteristics of the images.
Shalom EO offers Standard and Custom Pixel Level Mosaic Filters. The sizes of our pixel level mosaic filters can be tailored according to the sizes of the pixel size of the detector to achieve coordinating alignment between spectral channels and detector pixels. Featuring a highly integrated pattern of numerous spectral channels, our pixel level mosaic filter stands out when used as a spectroscopic element in an imaging spectrometer with the advantage of miniaturization and the lightweight design of the imaging spectrometer. An imaging spectrometer utilizing our pixel level mosaic filter as the core component can work in video imaging mode, overcoming the defect of the traditional imaging spectrometer that requires push-scan imaging and greatly improving the efficiency of spectral imaging. It can be applied in many high-precision fields such as camouflage identification, precision agriculture, geological survey, medical monitoring, and so on.
