1. A method of manufacturing a perforated member comprising:
providing a metal sheet:
masking a first side of the metal sheet to expose one or more defined areas;
masking the second side of the metal sheet with a mask on the opposing sides of the one or more defined areas, the mask on the second side comprising a plurality of perforations within the one or more defined areas;
etching the metal member to form a plurality of perforations through the metal member for the transmission of light through the perforations;
infilling the perforations through the metal member by causing molten light-transmitting thermoplastic polymer infill material to flow into the perforations; and
cooling the light-transmitting infill material after the light-transmitting thermoplastic polymer infill material flows into the perforations to solidify the thermoplastic polymer infill material to form a light-transmitting solid material.
