Abstract

The new generation of sub-10µm pixel pitch bolometers are currently arriving on the market for uncooled LWIR detectors. Pixel pitches are now starting to get smaller than the wavelength of light. The effect on the requirements for new lenses is still an open question, which in turn relies on the increased efficiency of this new generation of micro-bolometers. This study looks into the possible improvements expected on the lens side, whether it is needed to compensate the lower performance of the detectors and at what cost.
