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.

It is well suited for field research, yet compatible with all imaging platforms (airborne, benchtop, or outdoor). For a compact, lightweight Visible light spectral range option, please see the Pika L. For higher imaging speeds, please see the Pika IR-L. | Specim FX10+ The Specim FX10+ is a high-speed line-scan hyperspectral camera optimized for applications requiring fast imaging. Its high resolution ensures accurate and detailed imaging at a rapid pace. Specim FX10+ operates in the visible and near-infrared (VNIR) region from 400 to 1000 nm. | 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. | Pika UV 330 - 800 nm Ultraviolet + Visible The Pika UV (formerly NUV2) is a hyperspectral camera that scans the Visible and Near Ultraviolet (VIS+NUV) spectral range. An optimized objective lens provides excellent imaging throughout the entire spectral range. Because halogen lights have low output in much of the NUV, Resonon offers an NUV lighting module to augment illumination for our desktop system. The Pika UV can be used in our airborne, laboratory, and outdoor hyperspectral systems, as well as standalone or integrated into your system. | Pika IR-L 925 - 1700 nm Lightweight Infrared The Pika IR-L is a lightweight and compact Near-Infrared (925-1,700 nm) imager. 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. |
