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.

It can reveal the targets? chemical composition, moisture, and foreign objects that are invisible to the human eye. Specim FX17 can, for example, detect different plastic types for recycling and measure the sugar level of fruits and vegetables and the moisture percentage of baked goods. | HySpex Baldur S-384 N Baldur S-384 N covers the spectral range from 960-2500 nm. 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-384 N is better than 1.5 pixels, yielding a very sharp camera. | HySpex VNIR-3000 N HySpex VNIR-3000 N is developed for field, laboratory, and airborne applications. HySpex VNIR-3000 N utilizes the same spectrograph as the other classical HySpex VNIR models. With a pixel size of 3.45?m, compared to 6. 5?m for VNIR-1800, HySpex VNIR-3000 N will have less than 1.6 pixels per FWHM of the PSF spatially and less than 1.8 bands spectrally, ensuring that narrow band features will be resolved equally for all cameras. With 3000 spatial pixels, 300 bands and a noise floor of 2.4e-, HySpex VNIR-3000N will provide outstanding SNR levels in dark environments. The camera is offered with a USB connection, allowing camera operation from any computer and reducing the cost of supplementing equipment. To visualize that the camera has a wider PSF per pixel and band relative to our normal extremely sharp cameras, we have added an N for Nyquist to the model name. | Specim AFX10 Specim AFX10 is a VNIR hyperspectral imaging solution with an HSI camera, a small and powerful computer and a high-end GNSS/IMU unit in a compact enclosure that can be installed on multiple drone types. | 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. |
