Qtechnology cameras can be used for applications based on different inferred imaging technologies beneath the visible colour spectrum.

NIR (650 – 950 nm)
By replacing infrared filtering in the cameras while using NIR enhanced image sensors, our cameras can be used for near-Infrared Imaging imaging.



SWIR (900 – 1700 nm)
With special InGaAs sensors, the Near-infrared imaging spectrum can be increased to cover up to 1700 nm. Using InGaAs sensors, it is further possible to use our cameras for hyperspectral imaging, spectroscopy, biological imaging, water/moisture detection, industrial sorting, Internal defects, etc.

LWIR (8 – 14 um)
LWIR applies uncooled microbolometer sensors, which can be used for industrial thermal imaging such as building inspection, industrial insurance inspection, industrial process control, etc.

Visible light imaging technology is the majority of industrial machine vision applications. In particular, in applications where colour is an important characteristic. However, many applications require very specific light wavelengths to emphasise certain features of the object of interest.

If the colour of the feature of interest is known, using a similar wavelength of colour LED will highlight this specific feature. For instance, green light makes green features appear brighter while red light will make green features appear darker.

At Qtechnology, we can optimise vision systems by customising different coloured LED modules or combinations specifically to each client application

Some vision solution requires our multi-spectral or hyperspectral imaging technology.

Multispectral imaging is a combination of a few bands of the spectra at the pixel level. An example is our 3 CCD camera where each colour spectra is optically separated in red, green and blue and recorded at pixel level on three CCDs one per colour.”

With the use of low noise sensors, hyperspectral image cubes can also be captured using spectrographs or specialised sensors with narrow-band spectral filters at the pixel level.

These cubes can be used for spectroscopy to identify spectral features and signatures of different materials. It is not only used to separate specific materials but also to make qualitative measurements of the analysed objects.

By combining our low noise image sensors with scintillators, we also provide cameras that can be used for x-ray imaging.

This technology can, for instance, be used for the detection of metal, internal damages, hidden components, cracks, welding flaws, and determination of dimensional measurement.
