Abstract
A sorting or classifying apparatus comprising an illumination device for providing illumination or foreground illumination, the illumination device comprising a reflector () which has a reflecting surface () providing a reflection envelope, a first light source () which is disposed in spaced relation in front of the reflecting surface () and provides light of a first spectral output to the reflecting surface () for reflection thereby and which first light source () comprises a plurality of light elements or incandescent lamps (), wherein the light elements or lamps () are disposed on or near a focal axis (X) of the reflector (), and a second light source () which is disposed in spaced relation in front of the reflecting surface () and provides light of a second spectral output, different to the first spectral output to the reflecting surface () for reflection thereby and which second light source () comprises a plurality of light elements or light-emitting diodes (LEDs) () arranged along at least one row () which extends along the length of the reflecting surface () and is arranged in a direction substantially parallel to the focal axis (X) of the reflector (), optionally the first light source () is a source of near infra-red (NIR) light and the second light source () is a source of visible-spectrum light.
