Adept Turnkey offers a range of hyperspectral components and systems from Specim. Hyperspectral imaging produces image sets (Image Cubes) with spectral information that is broken down into very narrow spectral bands. Human sight senses three primary colours, Red, Green and Blue. Each of these colours denote a wavelength band of around 100 nanometres (nm). Hyperspectral imaging produces bands of just a few nm.

Specim hyperspectral products use the push-broom technique. Light enters a narrow slit and a spectrometer separates the light orthogonally to the slit into its discrete wavelengths not unlike what happens when a rainbow is created. The slit is parallel to the horizontal axis of the sensor so the vertical columns of the sensor detect the spectral spread. Each adjacent pixel in a column on the sensor detects a slightly different wavelength from the pixel above or below it. The push broom technique works much like a linescan camera. A single hyperspectral image represents the different wavelengths for a row of spatial pixels. By repeatedly capturing images of an object or scene as it moves past the sensor an image cube is captured and contains the spectrally separated information for the whole scene. Information about the materials in the scene can be determined since all materials and compounds absorb and reflect specific wavelengths in a unique way. By analysing the spectral nature of a scene with hyperspectral it is possible to determine what materials and compounds are in the scene.

Hyperspectral imaging is used for a number of different applications. These include agricultural applications - biomass mapping, crop disease detection, fire management; mining applications - exploration, core-logging, minerals seam tracking; defence and police applications - land mine detection, cannabis detection; forensics applications - crime scene details; water applications - bathymetry, hydrology; food applications- quality; pharmaceuticals applications- quality.

Adept Turnkey supplies all parts of a hyperspectral system - Fore lens, spectrometer, Spectral cameras, systems - core logging, chemical analysis, airborne. Our systems cover wavelengths from 400nm to 14um.
