nBn sensor technology allows higher operating temperatures with similar performance to InSb. This allows using smaller coolers with longer cooler lifetimes and lower power consumption. The nBn material long wave cutoff wavelength can be tuned from below 2 µm to longer MWIR wavelengths.
Longer wavelengths require slightly higher operating temperatures. For example, typical operating temperature for 4.2 µm cutoff nBn material is in the 150 K to 165 K range.
