HERA IPERSPETTRALE is a compact and rugged camera that enables an innovative approach to spectral imaging.
With its unique and patented technology based on time-domain Fourier Transform (FT) detection, HERA provides exceptional spatial-spectral resolution and superior sensitivity in low-light illumination conditions.
HERA is based on a Fourier Transform (FT) approach: the data-cube is acquired in the time-domain, by step-scanning a compact ultra-stable interferometer in front of the bidimensional sensor.
The software then automatically computes an FT at each and every pixel of the image, providing the final hyperspectral data-cube.
As a result of an FT, the spectrum at each pixel is a continuous curve, so the number of bands is virtually unlimited, not defined by the hardware.
As in any other FT techniques, the spectral resolution is not constant as a function of the wavelength. Also, the spectral resolution can be simply varied via software: at each measurement, you can decide whether to acquire a high spectral resolution-image, or – if not required – a faster and lower spectral resolution-image.
Regardless of this choice, the exceptional light throughput is not affected, thanks to the FT approach.

With a weight of less than 4 kg and less than 50 W power consumption, HySpex Mjolnir V-1240 is very well suited for a wide range of UAVs. The system is also compatible with several off-the-shelf gimbals. NEO offers high-performance unmanned aerial vehicles, fully integrated with the HySpex Mjolnir V-1240. The UAV is fitted with a standard battery package allowing up to 30 minutes of flight time. All HySpex Mjolnir systems can also be mounted on a tripod and rotation stage for ground use. | HySpex Mjolnir VS-620 For applications requiring low mass, combined with high-performance specifications and scientific grade data quality on the full VNIR-SWIR range, HySpex Mjolnir VS-620 is an ideal solution. Sharing the onboard data acquisition unit and navigation system, HySpex Mjolnir VS-620 is both space-efficient and cost-effective. The VNIR and SWIR optical axis are coaligned in the along-track direction, assuring perfect coregistration in the flight direction. In addition to the high-quality hyperspectral data cube, covering the spectral range from 400 - 2500 nm, with 490 bands, double resolution data in the VNIR range is always readily available. With smile and keystone less than 0.1 pixels for each spectral range, the merged Mjolnir VS-620 data product will have coregistration/keystone better than 0.2 pixels for the full VNIR-SWIR range. | Specim FX10 Specim FX10 is a line-scan hyperspectral camera that operates in the visible and near-infrared (VNIR) region. It is an excellent tool for industrial and scientific applications. The Specim FX10 operates in the 400-1000 nm region, and the color-optimized Specim FX10c in the 400-780 nm region. | SWIR SWIR is a high-speed short-wave infrared hyperspectral camera that operates in the 1000-2500 nm range. It has 384 spatial pixels and achieves image rates of up to 400 frames per second using a CameraLink connection. To assure indoor/outdoor usage in varying conditions, it now has rugged weather-proof IP54 casing and temperature-stabilized optics but still uses less power than before, only 50W nominal. Its temperature-stabilized optics provide stability and sensitivity required in the most challenging near-infrared chemical imaging applications, from pharmaceutical quality assurance to food and agriculture analysis. The SWIR camera meets the highest requirements in the lab, industry, and field. | Fenix FENIX is optimized for the most demanding geological, law enforcement, and environmental applications. In a single continuous image, FENIX spectral camera delivers the best hyperspectral data ever seen over VNIR, NIR, and SWIR wavelengths. FENIX offers extreme ruggedness and 75% reduction in size and weight compared to previous multi-sensor systems. The excellence in technical performance and physical size has been achieved through innovative and unique ?single optics dual spectrograph? design. |
