New generation of superlattice cameras add more ‘color’ to night vision

Recent breakthroughs have enabled scientists from the Northwestern University’s Center for Quantum Devices to build cameras that can see more than one optical waveband or “color” in the dark. The semiconducting material used in the cameras – called type-II superlattices – can be tuned to absorb a wide range of infrared wavelengths, and now, a number of distinct infrared bands at the same time.
