Spectral Characteristics Of Detection Systems
Camouflage is the use of disguise and concealment to minimise the possibility of detection.
By definition, camouflage technology covers a very broad spectrum and with modern developments in sensors and detection systems operates not only across the electro-magnetic spectrum but across the entire length of the energy spectrum as well.

Colour, although only covering a small portion of the available spectrum is extremely important for camouflage. Modern technology has extended the strictly visible function of colour to the ultraviolet and near infra-red portion of the spectrum and can offer an improved deceptive picture for modern sensors from 250 nanometers to 1200 nanometers and beyond.
The sensors that are commonly used are photo reconnaissance on the ground and in the air. Both use regular and infra-red sensitized colour and black and white films for visible and invisible radiation detection.
Apart from the visible spectrum (400 - 720 nanometers) the significant infra-red region with respect to camouflage is from 700 to 900 nanometers and most specifications use this region. This region is important because the spectral characteristics of chlorophyll are very noticeable in this wavelength region, although virtually every chlorophyll containing species has its own infra-red reflectance characteristics. This results in pigment systems being specific to particular environmental regions or applications.
Colour matching techniques are, though necessity, entirely instrumental for the majority of infra-red applications and Blythe's pigment expertise is fully backed up by computerised, instrumental colour measurement equipment. This ensures complete reproducibility throughout the Keraflect pigment range.
