NLIR - Infrared Unleashed. At NLIR (Non-Linear-Infra-Red), we offer innovative optical sensing solutions that enable new measurement, monitoring, and optical investigation possibilities for many different industries and research areas. We manufacture a range of products including mid-infrared spectrometers, broadband and narrow band wavelength converters from MWIR to VIS/NIR, light sources and a variety of optical interfaces.

Our products offer orders of magnitude faster spectral scans and sensitivity compared to traditional infrared spectrometers.These benefits have been made possible through our radically new, patented technology based on up-conversion of light from the mid-infrared to the visible/near-infrared wavelength region.
