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.

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-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. | HySpex Mjolnir V-1240 The HySpex Mjolnir V-1240 hyperspectral imaging system for UAVs 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 kg and less than 50 W power consumption, HySpex Mjolnir V-1240 is very well suited for a wide range of UAVs. The system is also compatible with several off-the-shelf gimbals. NEO offers high-performance unmanned aerial vehicles, fully integrated with the HySpex Mjolnir V-1240. 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. | 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. | Pika IR 900 - 1700 nm High-Speed Infrared The Pika IR (formerly Pika NIR-320) is a high-speed, cost-effective hyperspectral camera that covers the Near-Infrared (NIR) spectral range. It is our most popular imager for machine vision applications. The Pika IR can be used in our airborne, laboratory, and outdoor hyperspectral systems, as well as standalone or integrated into your system. |
