The Hertzstück™ lead sulfide (PbS) detector is a short wave infrared (SWIR) semiconductor sensor for 1 – 3 µm wavelength. Thanks to its thin-film encapsulation, Hertzstück™ is the first bare chip lead salt photoconductor that can be wire-bonded to printed circuit boards. Using this chip-on-board (COB) technology Hertzstück™ enables devices to be smaller, more flexible and more efficient.
