Axiom Optics is excited to announce a new partnership with Danish manufacturer of the fastest and most sensitive Mid-Infrared Spectrometer and detection tools. The core technology in these products is based on a novel measurement scheme that upconverts the Mid-IR light to the near-visible, where silicon-based light detectors outperform conventional Mid-IR detectors in all aspects: speed, sensitivity, and noise.
The NLIR Mid-IR product line offers the benefits of Mid-IR light upconversion in different packages that can cover many measurement needs:
Spectrometer 2.0 – 5.0 µm
With a full-spectrum readout rate of up to 130 kHz, -80 dBm/nm sensitivity, this instrument allows the fastest analysis in gases, liquids, and solids in industrial and research applications. Other readout rates and a wavelength range of 7.6 – 12.0 µm are available as well upon request.
Single-Wavelength Detector
Detection of a single-wavelength in the Mid-IR using a tunable instrument allows measurement rates of up to 10 GHz with the lowest noise by using narrowband upconversion of free-space or fiber-coupled signals.

Wavelength Conversion Module
This is the core-technology of NLIR products offered in a compact package. The most versatile product for any custom application, accepting wavelengths from 1.9 – 5.3 µm with a resulting resolution of 2.5 cm-1, or better, for the upconverted light.
