A radiation modifying apparatus comprises a plurality of solid state
radiation sources to generate radiation that modifies a first material
such as by curing or creating alignment through polarization. The solid
state radiation sources can be disposed in an array pattern. Optical
concentrators, arranged in a corresponding array pattern, receive
radiation from corresponding solid state radiation sources. The
concentrated radiation is received by a plurality of optical waveguides,
also arranged in a corresponding array pattern. Each optical waveguide
includes a first end to receive the radiation and a second end to output
the radiation. The radiation modifying apparatus can be utilized for
continuous substrate, sheet, piece part, spot curing, and/or 3D
radiation-cure processes.
