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 CMOS 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.
Thanks to the absence of aperture slits and gratings, and to the 1 cm Clear Aperture, HERA is specifically designed to provide an extremely high light throughput, making it the ideal device for low light conditions or delicate samples.

HySpex SWIR-640 offers high spatial resolution by using a unique MCT sensor. The FPA is cooled to 150K using a sterling cooler, yielding low background noise, high dynamic range, and exceptional SNR levels. The camera offers an aberration-corrected optical system with high optical throughput (f/2.0), the data quality, sensitivity, and resolution 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 32 ?m, to infinity for e.g. airborne remote sensing. | Pika L 400 - 1000 nm Lightweight, Compact VNIR The Pika L is a lightweight, compact hyperspectral camera that covers the Visible + Near-Infrared (VNIR) spectral range. It is our most popular imager for remote sensing applications. The Pika L can be used in our airborne, laboratory, and outdoor hyperspectral systems, as well as standalone or integrated into your system. | 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 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. |
