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-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. | 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.

The small size and mass make it well suited for airborne applications, where it can provide invisible to the naked-eye contrast of outdoor features. For a compact, lightweight Visible light spectral range option, please see the Pika L. For a higher spectral and spatial resolution version of the Pika IR-L, please see the Pika IR-L+ imager. | HySpex VNIR-1800 The HySpex VNIR-1800 hyperspectral camera is developed for field, laboratory, and airborne applications. HySpex VNIR-1800 utilizes a cutting edge actively cooled and stabilized scientific CMOS detector. This makes VNIR-1800 the ideal camera for high-end data acquisitions where high radiometric accuracy is required. The dynamic range of 20 000 ensures outstanding SNR levels even in darker areas of an image of highly dynamic scenes. With a max frame rate of 260 fps, combined with aberration-corrected optics and high optical throughput (f/2.5), HySpex VNIR-1800 offers a unique combination of data quality, high speed, and sensitivity. 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 24 ?m to infinity e.g. airborne remote sensing. |
