Abstract
A dichroic filter system for delivering UV to induce crosslinking of photocurable organic compounds on a substrate, whereby substantially all the UV is reflected to the workpiece while undesired infra red light is transmitted and absorbed by a dichroic filter and absorber arrangement. The filters are arranged so that substantially all the UV light from a line source of light strikes a dichroic surface only once and substantially all the UV light leaving the system has struck a dichroic surface once.
