The colours of vehicles, uniforms and equipment need to be suitable for camouflage. NATO specifies the green for fertile environments and the drab for desert use.
These colours are specified for light wavelengths from 350 to 1200nm. The specification used during manufacture defines a maximum and minimum reflectance at each wavelength. The light reflected from most surfaces is diffusely scattered in all directions above the surface. This light is collected by means of a sphere with an almost pure white surface called an integrating (or Ulbricht) sphere. The collected light eventually reaches the detector mounted out of direct sight from the sample.

A Camspec Double Beam UV/Visible Spectrophotometer can be simply converted from a conventional spectrophotometer into a NATO colour measurement system by the addition of an integrating sphere and special PC software. This scans the sample and prints out the reflectance at 10nm data intervals, together with a graph showing the reflectance and the maximum and minimum permitted values.
The Camspec M550N System used in-house during process control saves the time and expense of sending samples out to a testing laboratory.
