FAQs - Hyperspectral Imaging FAQ
What is Hyperspectral Imaging?
Every single point in an object has its own specific spectral fingerprint – the spectrum. Spectra can be used to identify and separate different materials and objects.
A hyperspectral camera collects and processes information by measuring the light interaction (reflection, transmission or emission) in order to obtain the Spectrum – the fingerprint - for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes

What are some of the applications of Hyperspectral Imaging?
Hyperspectral cameras can create images that:
- Accurately measure colors for printing processes, art restoration and other uses where color accuracy is critical
- Detect and identify materials in the life sciences, forensics and other scientific uses
- Map chemical compositions for the food industry, waste management and pharmaceutical analysis
- Remotely sense minerals and substances in geology, environmental studies and mining.

What is a Push-Broom camera?
A push broom scanner (also known as an along-track scanner) is used for obtaining images using hyperspectral cameras.
The scanners are regularly used in spectral analysis on production lines, food quality assurance, and for passive remote sensors in space.
SPECIM push-broom features:
- Transmission grating for highest diffraction efficiency over broad spectral range
- Practically independent of polarization
- Proprietary refractive or reflective/refractive spectrometer design for sharp image and sub-pixel keystone and smile
- Robust construction, high environmental stability
