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.

Similar to the VNIR version, it provides a unique combination of small form factor and low mass, combined with high-performance specifications and scientific grade data quality. With a weight of less than 4.5 kg and less than 50 W power consumption, HySpex Mjolnir S-620 is very well suited for a wide range of UAVs. NEO offers high-performance unmanned aerial vehicles, fully integrated with the HySpex Mjolnir S-620. 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. | Specim FX50 Specim FX50 is the only hyperspectral camera on the market covering the full mid-wave infrared (MWIR) spectral range of 2.7 - 5.3 ?m required, for example, in black plastics sorting. Specim FX50 is a high-speed, accurate, and efficient line-scan hyperspectral camera designed specifically for industrial environments. | HySpex Baldur S-640i N Baldur S-640i N covers the spectral range from 950-1730nm. All Baldur cameras are Nyquist cameras giving a spectral resolution of 2 spectral bands while capturing 4 times as much light as the classic systems. To ensure that the most information per framerate is provided, the spectral resolution is kept very close to 2 bands. Additionally, the spatial resolution of Baldur S-640i N is better than 1.5 pixels, yielding a very sharp camera. | 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. |
