About us

NLIR is a start-up company founded by 3 researchers at the Department of Photonics Engineering at the Technical University of Denmark (DTU Fotonik) and NLIR’s CEO. NLIR 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 detection of MIR light.

Our non-linear mid infrared spectrometer implementation represents a revolutionary new measurement paradigm. Our company is named Non-Linear InfraRed sensors (NLIR) to highlight our products technological difference from todays leading MIR spectrometry method of Fourier-Transform InfraRed spectroscopy (FTIR).

We target several industry sectors: Oil and gas, Polymer, Food and Agriculture, Pharmaceutical, Chemical, Medical Diagnostic and Environmental.
