Company Description
NLIR provides innovative mid-infrared sensors. Our spectrometers have a unique combination of fast spectral acquisition, high sensitivity and high resolution. Our uncooled mid-infrared detectors are shown to be even more sensitive than cryocooled detectors.
Our sensors are based upon a novel measurement paradigm, converting mid-infrared light to near visible light. This enables the use of uncooled silicon-based sensors for detection of mid-infrared light.
Our products target research groups at public institutes and private companies. As well as productions departments with a need of in-/on-/at-line MIR spectroscopy measurements across several industry sectors: oil and gas, polymer, food and agriculture, pharmaceutical, chemical, medical diagnostic and environmental.

Products
| Product Category | Description |
|---|
| mid-infrared spectrometers |  NLIR's MIDWAVE Spectrometer is designed for fast and accurate spectral measurements in the mid-infrared (MIR/MWIR) range of 2.0 – 5.0 µm. This portable and versatile instrument is capable of capturing full spectra in milliseconds, making it suitable for both laboratory and field applications.
|
| nonlinear frequency conversion equipment |  NLIR's SPEKTRUM Wavelength Converter efficiently converts wavelengths from 1.9 – 5.3 µm in the mid-infrared to 682 – 886 nm in the visible/near-infrared (VIS/NIR). This conversion is simultaneous and does not require time lag or scanning elements. The output is compatible with standard fiber-coupled grating spectrometers or silicon-based sensors. NLIR's TUNE Wavelength Converter is optimized for high conversion efficiency within a narrow bandwidth, ideal for sensitive mid-infrared light measurements. It operates over a tunable range from 2.7 – 4.3 µm, with the converted light shifted to 763 – 853 nm, suitable for any fiber-coupled detector operating in these near-infrared wavelengths. The TUNE Wavelength Converter is particularly effective for detecting narrowband signals, whether weak or rapidly varying. It supports measurements with time-gated PMT, SPAD detectors, APDs, and high-speed PIN photodiodes. Now you can read mid-infrared data with your VIS/NIR spectrometer/detector. |
| spectrometers |  NLIR's MIDWAVE Spectrometer is optimized for rapid and precise spectral measurements in the mid-infrared (MIR/MWIR) range of 2.0 – 5.0 µm.
NLIR's BUNDLE Spectrometer offers fast and accurate spectral measurements in the MIR/MWIR range of 2.0 – 5.0 µm. When combined with high-end VIS/NIR spectrometers, it provides enhanced capabilities with readout rates of either 1.4 kHz or 130 kHz, a minimum detection power of 5 pW/nm, and a resolution of 6 cm−1. NLIR's CUSTOM Spectrometer can be tailored to meet specific requirements for spectral measurements in the mid-infrared wavelength range. |
| spectroscopy equipment |  A selection of our interfaces and accessories allows you to perform spectroscopic measurements a lot easier and faster. Explore our full product catalogue for various application measurements! |
| thin-film measurement systems |  NLIR offers a comprehensive Transmission Measurement System designed for thin-film measurements. The system includes:
This system provides high signal output and extensive data. Note that for foils thicker than 1 mm, light transmission may be insufficient for effective spectrometer analysis. |
