| Résumé: | This project summarizes the work done as part of a master's degree in applied optics and photonics with the aim of studying the contribution and improvement of the surface condition of polished optical glasses. The main objective of this study is to be able to replace traditional abrasive particles based on cerium oxide with new materials having almost the same properties but available in larger quantities and at lower cost.This experiment is applied with gypsum (CaSO4.2H2O)We obtained excellent results, among which we mention:Roughness Ra = (2 ± 0.2645) nm andRq = (3.6 ± 0.4804) nm at the optimal polishing time of 45 minutesTransmission of (92.3 ± 30.68)% after 45 minutes of polishing. |
