Scientific research labs and the industrial sector can exploit the power of spectroscopic analysis to monitor the quality of their processes and the properties of their products.

Continuous Research & Innovation. NIREOS team of professors, researchers and PhD students is constantly focused to keep generating ground-breaking and trustworthy solutions in the light and photonics sector.




GEMINI Interferometer:

Need a spectrometer for low-light applications, such as fluorescence? Look no more! GEMINI is a novel and compact interferometer with unprecedented throughput and bandwidth, from the UV to the visible and near-infrared.


GEMINI-2D Interferometer:

Advanced GEMINI model, specially designed for two-dimensional electronic spectroscopy (2DES) experiments. It keeps constant both the dispersion during the scan of the relative delay between the two generated replicas of light and the absolute arrival time of one of the two replicas (with attosecond stability).


HERA Hyperspectral Camera:

A compact and rugged hyperspectral camera. HERA provides an innovative approach to spectral imaging and offers superior sensitivity to low-light illumination conditions and access to the continuous spectrum from the visible to the near-infrared.


SPECTRE Spectrometer:

Ultra-broadband spectrometer, capable of measuring ultrabroadband spectra, from the VIS to the MID-IR spectral region. Combines fast acquisition times and high spectral resolution with extremely broad spectral coverage.


NIREOS technology is based on Fourier-transform (FT) spectroscopy, a technique that uses interference of light rather than dispersion to measure spectra. Light is split in two collinear time-delayed replicas, whose interference pattern is measured by a detector as a function of their delay. The FT of the resulting interferogram yields the continuous-intensity spectrum of the waveform. FT spectrometers have prominent advantages over dispersive ones:

(i) higher signal-to-noise ratio in a readout-noise-dominated regime (multiplex or Fellgett’s advantage);

(ii) higher throughput and increased system étendue, due to the absence of slits (Jacquinot’s advantage);

(iii) higher wavelength accuracy (Connes’ advantage).

Moreover, FT spectrometers provides a flexible spectral resolution, which is adjusted at will by varying the maximum scan delay and does not affect the throughput of the device.
