Abstract
Filters, 28.5 x 74 cm, which divide the visible and near-visible spectrum into 8 fairly well-defined regions were built from transparent colored plastics; Perspex (Imperial Chemical Industries Ltd.) and Plexiglass (Rohm and Haas Co.). The plastics were cut and fabricated as enclosed tanks using combinations of colored or colored and clear plastic as top and bottom of the tank. These were filled with the required concentrations of aqueous copper sulphate to obtain the desired spectral divisions. A 5 cm enclosure around the top for flowing water coolant permits use of high intensity light sources.Keywords
