Abstract
Abstract Transparent selective optical absorption filters of improved stability to ambient solar light and radiation in the near UV range are provided by incorporating metallized tetra ((meso)-5-methyl-2-thiophene) phorphines, platinum (5-bromo octaethylporphine) or mixtures thereof into suitable filter matrices such as plastic, glass or the like. Optical filters absorbing in narrow radiation bands and useful as transparent protective laser shields are provided.
