A method and system of sorting materials from a material stream on a sorter is provided. The heat source and the high-efficiency diamond material have a contact area greater than 1 square centimeter. The lamp further comprises a vertical metallic post, the post being grounded to the metallic lamp body at the post’s bottom surface. In the illustrated embodiment, integrated circuits with patterned contact pads are passed through one of the upper compartments, in which oxide is removed from the contact pads. The output string is utilized as a geographic indicator with a URL. The adhesive material is filled into gaps between the engaged protrusions to fixedly interconnect the first lens and the second lens.
