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 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 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 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. | Pika IR-L+ 925 - 1700 nm Lightweight, High-Precision Infrared The Pika IR-L+ imager is a high spatial and spectral resolution Near-Infrared (925-1,700 nm) imager in a lightweight, compact format. 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. |
