Impedance matched coatings are used for absorber applications to couple mid-to far-infrared (IR) radiation to an ultrasensitive bolometric detector suspended on an ultrathin dielectric membrane. In order to provide adequate responsivity, the bolometric detector must have a low heat capacity. Furthermore, to achieve an optimal signal-to-noise ratio, spectral filtering of the incident radiation is desirable.
