Measure hot samples at any distance - in real time
NLIR’s mid-infrared spectroscopy solutions offer rapid measurements of various objects at all distances. Light from combustion processes or other hot samples is caught just by pointing the fiber head towards it. With millisecond readout time, measure combustion emittance and detect composition of various samples in real time.
Experience instant results
Our MIR upconversion spectrometers outperform conventional MIR spectrometers in detectivity, speed, and noise. Measure samples in real time, even if the objects are moving. See for yourself!
Analyze combustion processes
Analyze products of combustion of hydrocarbons (methane, ethane and other alkanes): carbon dioxide (CO2), carbon monoxide (CO), water (H2O), ammonia (NH3), nitrogen oxides (NOx), sulfur dioxide (SO2), and other gases in real time.
Simple solution to a complex need
Temporal precision, high speed, and great flexibility – all in real time! NLIR's spectrometers are engineered for effortless light capture with its convenient fiber coupling and high sensitivity.

7.6-12.0 µm Spectrometer
Covering most of the upper infrared atmospheric window, this free-space-input 7.6 - 12.0 µm spectrometer is perfect for rapid measurements at a distance.
How does it work?
Using NLIR’s spectrometers for monitoring of combustion process or other hot objects at a distance is straightforward. Just set up your devices, plug it to our software, and get readout data as you go.
Experience our breakthrough technology
-80 dBm/nm sensitivity allows NLIR spectrometers to measure light from sources kilometers away.
The NLIR spectrometer measures spectra in only milliseconds. The integration time can vary from 100s of ms down to 11 µs depending on the need. The external trigger can be used to optimize the data capture timing.
NLIR’s spectrometers use detector arrays with 2048 pixels, so the resolution can be as low as 2.5 cm⁻¹ in a wide optical bandwidth.
NLIR’s spectrometers are so fast because they use an array detector that can read out data with 400 Hz and even up to 130 kHz.
The NLIR Spectrometers are based on a novel measurement technology that upconverts the MIR light to near-visible light. The near-visible light can then be detected by silicon-based CMOS detector arrays.
