ive sorting machines, which are able todetect and remove the smallest of defects and foreign material from production lines.
TOMRA machines use a variety of sensors which go beyond the common use of colour cameras.
Near infrared (NIR) spectroscopy enables an analysis of the molecular structure of a product while x-rays, fluorescent lighting and lasers measure the elemental composition of objects.
The internal composition and surface structure of objects can also be analysed to determine good
