Single-Wavelength Detector Details
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 single-wavelength 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.

Measurement of mid-IR ns Pulses
Light from an NKT Photonics MIR Compact supercontinuum source, which emits 5 ns pulses at 40 kHz covering a spectrum from 2 µm to 4.2 µm, is measured using two different point detectors. A MIR monochromator selects the wavelength 2.4 µm with a 20 nm bandwidth, and the output is coupled to a 200 µm MIR fiber. The output of the fiber is sent in turn to each of two detectors: an NLIR 240 MHz 2.4 µm Single-wavelength detector (with 50 dB attenuation) and a commercially available 9 MHz InAsSb detector with direct exposure. The figure shows the responses of the two detectors.
