LASER-ATTENUATIVE OPTICAL FILTER |
摘要 |
An optical filter for absorbing neodymium YAG-doubled laser radiation at 532 nanometers, comprising a polymeric matrix of transparent polycarbonate containing platinum deuteroporphyrin IX dimethyl ester, has an optical density of 1.8 at 532 nm while having a photopic luminous visible transmission of 53.8%. Optionally, the filter may contain other additives for absorption at other laser wavelengths, such as vanadyl tetra-4-tert-butylphthalacyanine for absorption of ruby laser radiation at 694 nanometors and tris(p-diethylaminophenyl) aminium hexafluoroantimonate for absorption of neodymium YAG laser radiation at 1064 nanometers.
