It is a highly reliable uncooled infrared focal plane array (IRFPA) detector for thermal imaging with high sensitivity, small size, light weight and low power.
It is a device sensitive to the radiation in the infrared range (LWIR, 8-14um) of the spectrum, also called thermal radiation.The focal plane has an array of pixels, which are made of VOx resistive microbolometers connected to the silicon readout integrated circuit (ROIC). The entire chip is assembled with a thermal electric cooler (TEC) inside a metal vacuum housing.
