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.

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. | 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 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. | 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. | HySpex VNIR-3000 N HySpex VNIR-3000 N is developed for field, laboratory, and airborne applications. HySpex VNIR-3000 N utilizes the same spectrograph as the other classical HySpex VNIR models. With a pixel size of 3.45?m, compared to 6. 5?m for VNIR-1800, HySpex VNIR-3000 N will have less than 1.6 pixels per FWHM of the PSF spatially and less than 1.8 bands spectrally, ensuring that narrow band features will be resolved equally for all cameras. With 3000 spatial pixels, 300 bands and a noise floor of 2.4e-, HySpex VNIR-3000N will provide outstanding SNR levels in dark environments. The camera is offered with a USB connection, allowing camera operation from any computer and reducing the cost of supplementing equipment. To visualize that the camera has a wider PSF per pixel and band relative to our normal extremely sharp cameras, we have added an N for Nyquist to the model name. |
