PROCESS FOR THE ABLASIVE WORKING OF OPTICAL ARTICLES MADE FROM CROSS-LINKED POLYMERS |
摘要 |
<p>An optical element made from crosslinked polymers is worked by ablative photochemical decomposition. To this end, the crosslinked polymer is exposed to controlled, coherent irradiation whose photon energy is significantly higher than the dissociation energy of the covalent bonds in the polymer and whose fluency is sufficient to remove the resultant decomposition products.</p> |
