Abstract

We report on the manufacture of a dual band uncooled infrared detector of lead selenide for smart detection of IR emitters. The first advanced bicolor PbSe sensor with its spectral response modified by design for our purpose has been developed by means of the monolithical integration of two high-pass interference filters and polycrystalline PbSe sensors. Wavelength cut-on of the filters was 3.7 and 4.3 μm. Room temperature detectivities of unfiltered lead selenide yield values of D*pk (3.6 μm, 330 Hz, 1 Hz) ∼ 10 9 cm Hz1/2/W. Considering the excellent properties of this MWIR sensor, the possibility of enhancing it with a selected spectral response opens its use to a wide range of applications. © 2013 Elsevier B.V.
