NLIR Thermal infrared light source
- fiber coupled
- Active cooling
- stability +/- 0,5%
Thermal infrared light source directly to your sample in an optical fiber. Infrared light or infrared radiation sources are used in a variety of applications and measurements. Compared to other light sources, high-temperature IR light sources are relatively cheap and require only simple electronics; they emit high-power light that is stable and reliable. However, due to the nature of the warm emitter, the light is incoherent and emitted in all directions, which makes it difficult to guide and focus the light onto a sample with high intensity. NLIR’s fiber-coupled IR light source makes it easy to bring MIR light to a sample either by positioning the fiber tip close to the sample or by using one of the many commercially available fiber-probes. The light source is plug-and-play, turns on in a few seconds, and is actively cooled so that no parts are too warm to touch.
NLIR Single-Wavelength Detector
- > 10 GHz bandwidth
- high sensitivity
- tuning optional
- optimized for 200um fiber
The greatest challenge for mid-infrared detectors is typically the substantial inherent noise and that they collect large amounts of radiation from the surroundings. Our detectors alleviates both limitations by using narrowband and efficient upconversion technology together with low-noise silicon-based detectors. Besides the excellent sensitivity, speed and low noise properties, the output of all our detectors is pre-amplified to voltage levels easily measurable with standard oscilloscopes. There is no need to apply further noisy amplification, all detectors are designed to be plug-and-play for user who are looking for the most sensitive mid-infrared detectors commercially available.
NLIR 7.6 – 12.0 μm
- extended range
- -67 dBm/nm sensitivity
- 50 Hz speed
- free space design
The mid-infrared region from 6 μm to 12 µm (1667 cm -1 to 833 cm -1 ) is very interesting for many industrial and research applications because many molecules have defining absorption lines exactly there. Unfortunately, the detectors (typically HgCdTe) used in FTIR systems for spectroscopy purposes suffer from significant amounts of thermal noise due to their low bandgap. Hence, high levels of input light are needed with long exposure times to achieve a satisfactory signal-to-noise ratio. NLIR is pushing its technology to cover this extended wavelength region in the future. Currently, the prototype edition of the long-wavelength spectrometer covers 7.6 μm to 12.0 μm (1316 cm -1 to 833 cm -1 ). The spectrometer is currently available with a 50 Hz full-spectrum readout rate and a resolution of 10 cm-1. The sensitivity is 200 pW/nm (-67 dBm/nm) with full aperture exposure. The prototype spectrometer has a large free-space input, which makes it easy to couple in lots of light and ideal for reference measurements (e.g. in ATR crystals, gas cell, sample transmission/reflection, etc.) with a fixed light source. Due to the large input, the response of the spectrometer is, however, sensitive to the angle of input, which makes an input power calibration necessary for the characterization of light sources.

NLIR 2.0 – 5.0 μm
- up to 130 kHz
- -80 dBm/nm sensitivity
- modular design
The NLIR S2050 MIR Spectrometer is based on a novel measurement scheme that upconverts the MIR light to near-visible light. Silicon-based near-visible light detectors are far superior to MIR light detectors in terms of detection, speed and noise. The NLIR upconversion technology therefore brings these attractive features, and the advantages that follow, to the MIR regime. The spectrometer is made in three editions: S2050-400 is the most sensitive with max. 400 Hz full spectrum readout rate; S2050-1k is faster and has better resolution but lower sensitivity; S2050-130k has the best resolution and the highest readout rate. All versions come with a GUI interface for easy plug-and-play measurements in various applications; additionally, API interfaces for MATLAB, Python and C (DLLs) are available.

Official partner of NLIR
NLIR is spin-off from the Department of Photonics Engineering at the Technical University of Denmark (DTU Fotonik) and is based on the novel patented upconversion technology invented by its founders at DTU Fotonik. The core of the upconversion technology is a non-linear crystal that converts mid-infrared light to near-visible light. This enables the use of fast and efficient Silicon-based sensors for the detection of MIR light. Their non-linear mid-infrared sensors represent a revolutionary new measurement paradigm (Resources). Their mission is to put forward innovative optical sensing solutions and help other industries overcome their challenges and discover the future. And that is exactly why Photon Mission is working together with NLIR. Their technology amazed us immediately. It makes MIR measurements easy, simple and accessible.
