 ==The Principle==
-The basic principle behind the NIR technology is measuring the wavelength the bounces off an object. The conveyor moves the material under a bright light which fires near infra-red wavelengths of light at the [[Recyclables|recyclables]]. Some of the wavelengths are absorbed while others are reflected by the material. The NIR sensors that are positioned in the last third of the conveyor record the characteristics of the wavelengths bounced back from the material. From there they are able to determine and target the different types of [[Recyclables|recyclables]] on the belt<ref name="ref2" />.
