Hertzstück™ PbSe lead salt near-infrared (NIR) detectors by trinamiX are available as single-pixel, multi-single-pixel and multi-pixel versions.

These PbSe detectors cover a wide NIR spectral range, which is highly relevant for applications in inline or mobile process analytics, quality control and gas sensing. The bare chips of trinamiX’ Hertzstück™ series PbSe lead salt near-infrared (NIR) detectors and detector arrays are protected by a unique thin-film encapsulation for longer lifetime and highest detectivity at room temperature.


Bare-chip solutions enable small, flexible and very efficient devices and can be directly wire-bonded to printed circuit boards. Single- and multi-single-pixel versions are also available on small, pre-bonded, solderable adapter PCBs, allowing customers without wire-bonding expertise or capabilities to benefit from the detectors’ patented thin-film encapsulation, pick and place compatibility, small footprint and large field of view.


Direct access to the thin-film encapsulated sensor surface without lossy entrance windows is crucial for compact solutions, applications with low signal levels, or optimal coupling with optical fibers. The adapter PCBs come in various sizes starting at 5 x 6 mm and a module height of 1 mm. Four castellated holes on the outer PCB edges serve as solder pads and make it possible to mount these detector modules directly onto any system PCB.

Beyond bare chip versions, the Hertzstück™ PbSe series single-pixel NIR detectors are also available housed in TO-packages with double encapsulation – not only protected by a standard TO package, but also by the thin-film encapsulation directly on the chip.


TO-packaged PbSe single-pixel NIR detectors are as well offered with an integrated thermoelectric cooler (TEC). All TEC-based trinamiX detectors incorporate a thermistor which allows for a precise temperature stabilization of the active element. The single- and two-stage TECs provide for operation at extremely low temperatures for increased detectivity and sensitivity at larger wavelengths independent of the ambient conditions.


Hertzstück™ PbSe multi-single-pixel bare chip NIR detectors consist of 2 to 16 single pixels in line or matrix design, wire-bonded on PCB. The usage of single pixel detectors enables high flexibility regarding setup and filters.


Hertzstück™ PbSe multi-pixel bare chip NIR detectors consist of 2 to 16 pixels in line or matrix design, realized directly on the substrate. This technology provides high durability for rugged operation as well as bondable electrodes for COB mounting and is suitable for automated wire-bonding.


Three different evaluation kits enable users to easily compare different varieties of the Hertzstück™ PbSe NIR detectors and to quickly develop circuit designs for their applications.
