Our core expertise is Fourier Transform Spectroscopy (FTS), with a particular focus on the far-infrared spectral range and a strong heritage in ground and space based astronomy. Due to their high efficiency and variable spectral resolution, single pixel FTS are the instruments of choice for many precision spectroscopic applications. Recent advances in detector array technology have also led to the emergence of imaging FTS as a leading contender in the field of hyperspectral imaging.

We have extensive experience with the mechanical, optical and electronic design, as well as scientific data analysis required for producing custom FTS instruments optimized for any application. We have built a wide range of spectroscopic systems from visible to submillimetre wavelengths (see our Products and Services pages for more details). Our FTS systems provide the highest commercially available optical throughput, which is of particular importance in the energy starved submillimeter spectral region.

Building on this pedigree, we also offer source, detector and full instrument calibration services for the mid-infrared, terahertz and sub-terahertz spectral range at resolving powers up to 10,000 from room temperature to 4K.
