Hyperspectral camera 900-2500nm

HERA-Ext-SWIR is a compact and rugged hyperspectral camera that enables an innovative approach to spectral imaging in the extended short wave infrared (SWIR: 900-2500 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.

Working principle:
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 InGaAs 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 hyperspectral camera NRS-HERA-Ext-SWIR:
- 900 - 2300 nm
- Spatial resolution 320 x 256 px.  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)
- Very low dark current
- Ideal for  stationary applications

The high throughput ensures high-quality data even at the lowest light dose.

Typical applications of the extended SWIR hyperspectral imaging systems:
- Remote sensing
- Identification and sorting of plastics, minerals and other materials
- Recycling
- Medical and biosciences; phamaceuticals
- Agriculture and food quality (agri-food)
- Pharmaceuticals
- Art conservation
- Forensics
- General applied and basic research
