Spectral Sensing Filters

There is a fascinating world to be seen beyond the range of human vision. Hyperspectral imaging – seeing beyond the visible spectrum with much more color detail – allows us to explore the invisible world that surrounds us.

Hyperspectral Filter Array (HFA) technology provides a manufacturing-efficient method of depositing and array of spectral bandpass filters. The filters can be produced on glass or direct-deposited on sensor wafers.

  • Near UV to mid-wave IR (300nm to 5µm)
  • Practical for 16 to 300 channels
  • Customizable spectral bandwidth and placement
  • Optional dark mask to minimize stray light
