Abstract
An element which is used to identify materials, such as, thermoplastics and sort these thermoplastics on a moving conveyor belt. Such structures of this type, generally, employ a diamond knife (or point) for use as an internal reflection element to obtain the mid-infrared spectrum of the material sliced (or punctured) by the knife (or point).
