HERA-VIS-NIR is a compact and rugged hyperspectral camera that enables an innovative approach to spectral image in the visble and near infrared (VNIR) 400 - 1700 nm.
With its unique and patented technology based on time-domain Fourier Transform detection, HERA provides an exceptional spatial-spectral resolution and a 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.
In our Polyespectral Imaging Application you can learn more on this technology, the features and advantages.
Key features of the VNIR hyperspectral imaging system NRS-HERA-VIS-NIR:
- 400 - 1000 nm
- High spatial resolution 1.3 MPx. All pixels are true image pixels. No interpolation is used.
- High spectral resolution
- Compact and lightweight; portable and plug and play
- Exports data in ENVI format
- Powerful and user friendly software (measurement & data analysis)
- Ideal for stationary applications
The high throughput ensures high-quality data even at the lowest light dose.
