Single-Wavelength Detectors

  • Up to 10 GHz electrical bandwidth
  • 2.2 – 5.0 µm center wavelength
  • Up to GV/W response
  • Free-space or fiber-coupled input
  • Plug-n-play with built-in pre-amplification

The greatest challenge for mid-infrared detectors is typically the substantial inherent noise and that they collect large amounts of noise from the surroundings. Our detectors alleviates both limitations by using narrowband and efficient upconversion technology together with low-noise silicon-based detectors. This is all done in our plug-n-play detector modules where the infrared signal is mixed with our high-power pump laser to produce a near-visible signal detectable by a versatile range of high response silicon-based detectors. In case you are not in the need for ultra-low signal detection we also offer broad-band solutions that compromise the efficiency but allow your broad-band sources into the regime of high-speed and low-noise mid-infrared detectors.  

Whether you are looking for the smallest or the fastest signals we believe that our portfolio of state-of-the-art mid-infrared detectors can serve almost any challenging measurement task you can imagine.  

Always plug-n-play, maintenance free and with built-in transimpedance amplifier.
