About Us


At NLIR (Non-Linear-Infra-Red) we enable the test and measurement industry to increase the throughput of their spectral mid-infrared quality control.

We manufacture a range of products including mid-infrared spectrometers, single wavelength detectors and light sources.

Our products offer orders of magnitude faster spectral scans and sensitivity compared to traditional infra-red spectrophotometers.

These benefits have been made possible through our radically new, patented technology based on up-conversion of light from the infra-red to the visible wavelength region.
