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.

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. | SWIR SWIR is a high-speed short-wave infrared hyperspectral camera that operates in the 1000-2500 nm range. It has 384 spatial pixels and achieves image rates of up to 400 frames per second using a CameraLink connection. To assure indoor/outdoor usage in varying conditions, it now has rugged weather-proof IP54 casing and temperature-stabilized optics but still uses less power than before, only 50W nominal. Its temperature-stabilized optics provide stability and sensitivity required in the most challenging near-infrared chemical imaging applications, from pharmaceutical quality assurance to food and agriculture analysis. The SWIR camera meets the highest requirements in the lab, industry, and field. | 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. | 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. | HySpex SWIR-384 The HySpex SWIR-384 hyperspectral camera is developed for field, laboratory, and airborne applications. The state of the art MCT sensor with cooling down to 150K yields low background noise, high dynamic range, and exceptional SNR levels. With a max frame rate of 400 fps, combined with an aberration-corrected optical system with high optical throughput (f/2), the data quality, speed, and sensitivity 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 53 ?m to infinity e.g. airborne remote sensing. |
