Title (EN) MECHANISM FOR IMPARTING WATER REPELLENCY TO BOTH SIDES SIMULTANEOUSLY
(FR) MECANISME SERVANT A RENDRE HYDROPHOBES DEUX COTES SIMULTANEMENT
Abstract:
(EN) A mechanism for imparting water repellency to both surfaces of each of optical lens blanks simultaneously is provided in a vacuum treatment chamber (16) in which water-repellent films are formed on both sides of each of optical lens blanks (24) arranged on a blank holder (22) which is placed in a vacuum atmosphere rotatably. An upper surface water-repellency treatment unit (30) and a lower surface water-repellency treatment unit (40) are provided above and below the blank holder (22). Water-repellent films are formed on the upper surfaces of the optical lens blanks by the upper surface water-repellency treatment unit, while water-repellent films are formed on the lower surfaces of the optical lens blanks by the lower surface water-repellency treatment unit. With this constitution, water-repellent films are formed on both sides of each of the optical lens blanks simultaneously. A film thickness correction mechanism for water-repellency treatment comprises film thickness correction plates (51, 52) which are provided between the upper water-repellency treatment unit and the optical lens blanks and between the lower water-repellency treatment unit and the optical lens blanks.
(FR) Mécanisme servant à conférer une caractéristique hydrophobe aux deux surfaces de chacune des ébauches de lentilles optiques simultanément et opérant dans une chambre de traitement sous vide (16) dans laquelle des pellicules hydrophobes sont créées des deux côtés de chaque ébauche (24) de lentille optique placée sur un support (22) positionné rotatif dans une atmosphère évacuée. Une unité de traitement hydrophobe (30) de surface supérieure et une unité de traitement hydrophobe (40) de surface inférieure sont situées au-dessus et au-dessous du support d'ébauche (22). Des pellicules hydrophobes sont créées sur les surfaces supérieures des ébauches de lentilles optiques par l'unité de traitement hydrophobe de surface supérieure, tandis que des pellicules hydrophobes sont créées sur les surfaces inférieures des ébauches de lentilles optiques par l'unité de traitement hydrophobe de surface inférieure. Ceci permet de produire simultanément des pellicules hydrophobes des deux côtés de chacune des ébauches de lentilles optiques. Un mécanisme de correction de l'épaisseur de la pellicule hydrophobe est composé de plaques (51, 52) servant à corriger l'épaisseur de la pellicule et situées entre l'unité de traitement hydrophobe de surface supérieure et l'ébauche, ainsi qu'entre l'unité de traitement hydrophobe de surface inférieure et l'ébauche.
