A new desing for high-sensitivity, low noise detection of mid-infrared light.  Coupled with our ultra-low noise laser controllers, The QubeDT differential detector opens a wide range of possibilities for advanced spectroscopy.

Two models are available:

• QubeDT-S: DC-coupled (0-2 MHz BW) detector, designed for spectroscopic applications such as Polarization Spectroscopy.

• QubeDT-F: AC-coupled, high BW (>1200MHz) detector, designed for heterodyne detection and RIN-immune beat-note acquisition.
