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 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. | 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. | Specim FX50 Specim FX50 is the only hyperspectral camera on the market covering the full mid-wave infrared (MWIR) spectral range of 2.7 - 5.3 ?m required, for example, in black plastics sorting. Specim FX50 is a high-speed, accurate, and efficient line-scan hyperspectral camera designed specifically for industrial environments. | 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. | 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. |
