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.

The state of the art MCT sensor with cooling down to 150K yields low background noise, high dynamic range, and exceptional SNR levels. With a max frame rate of 400 fps, combined with an aberration-corrected optical system with high optical throughput (f/2), the data quality, speed, and sensitivity is truly state of the art. A wide range of close-up lenses allows the use of the camera at working distances ranging from a few centimeters with a spatial resolution of 53 ?m to infinity e.g. airborne remote sensing. | 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 VS-1200 The HySpex VS-1200 hyperspectral camera is developed for airborne applications requiring extreme resolution in both VNIR and SWIR spectral regions. The HySpex VS-1200 is a novel high-resolution instrument designed for airborne applications at altitudes greater than 400m. The camera produces the highest scientific grade level data, commercially available, having FWHM less than 1.2 pixels spatially and less than 1.5 pixels spectrally. The combined VNIR-SWIR cube has coregistration errors, and smile and keystone of less than 10% of a pixel. With 40 degrees FOV, the camera is ideal for mapping large areas with high accuracy and resolution. The camera is delivered with an integrated high-performance IMU/GPS and data acquisition unit with removable storage bays as a standard. Existing navigation systems can also be integrated/utilized. A standard passive damping solution is included as a part of the default delivery package, but mounting plates for active damping solutions, such as GSM4000 or PAV80 can be supplied. | HySpex Baldur V-1024 N Baldur V-1024 N covers the full VNIR spectral range from 400-1000nm and is configurable within one octave in the same range. 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 V-1024 N is better than 1.7 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. |
