Abstract
The invention relates to an optical sorting system for a color sorting machine. Product is irradiated with visible, infra-red or ultra-violet light by a transmitter. If there is no product in the ray path of the transmission source, all of the light falls onto a residual light receiver. If product is present, on the other hand, the light is partly or wholly scattered back to one or more product signal receivers.
