The goal of this work was the development of an ocular filter for protection against laser radiation. In the plastic research phase of the work, copper II doped plastic materials were developed which have spectral characteristics that satisfy the absorption requirements at 694 and 1060 nm and have a luminous transmittance of 22. Plastics were also formulated using copper II salts plus an organic dye to produce a filter with an optical density of approximately 3.5 at 530 nm and below and at 1060 nm. The luminous transmittance of this filter was also about 22. These plastics which are castable, modified polyester materials had some crazing problems due to the modifying agent initially used. Subsequent changes in the modifying agent appear to have eliminated the crazing problem. Author, modified-PL
