One of the key measures to secure reliable fever screening is to calibrate a thermal imager with an accurate flat-plate blackbody device in real time. We provide durable perfect blackbody plates with both high emissivity of ${\gt}{0.998}$ and good heat transfer, ideal for a high-precision reference radiation source. Reflectance measurements and heat transfer simulation demonstrate that a micro-cavity composite of a thin resin double layer or resin mixture with thermally conductive filler is an important solution for improving the emissivity and thermal performance of blackbody plates.
