Bare Chip

IR Detectors Single-Pixel Bare Chip

Hertzstück™ bare chip infrared detectors are protected by a thin-film encapsulation. They can be directly wire-bonded to printed circuit boards. Bare chip solutions enable small, flexible and very efficient devices.

  • Bare chip
  • New encapsulation technology (patent pending)
  • Fully wire bondable
  • Readily available in large scale

PbS and PbSe bare chip detectors on solderable PCBs

BC detectors on PCBs

PbS and PbSe bare chip detectors on small PCB pre-bonded solderable adapter PCBs allow 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 mm 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.

TO Package (Transistor Outline package solutions)

IR Detectors Single-Pixel TO-Package

The infrared detectors Hertzstück™ are available with double encapsulation. The sensors are not only protected by a standard TO package, but also by a novel thin-film encapsulation directly on the chip.

  • Thin-film encapsulation for long lifetime and highest detectivity at room temperature
  • Additional TO package for increased safety, robustness and compatibility with existing products

Thermoelectrically cooled (TEC) PbS and PbSe detectors

Thermoelectrically cooled PbS and PbSe Hamamatsu replacement detectors

TO-packaged detectors are also available with 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.
