【摘要】 研究了光学元件镀膜前超高洁净度要求的超声清洗工艺,在超声波清洗机的频率和功率一定的情况下,通过研究超声清洗剂、清洗温度、清洗时间等对光学元件超声清洗效果的影响,研制出有效清洗光学元件的清洗工艺,并保障超声清洗工艺对光学元件的表面状况无损伤。同时发现光学元件的放置时间会影响元件的清洗效果。超声清洗刚加工好的光学元件洁净效果较好,清洗时间较短;有6个月存放期的光学元件,表面颗粒污染很难洁净清洗。更多还原

【Abstract】 The ultrasonic cleaning technology of uncoated optics with high cleanliness requirement is studied.The effects of ultrasonic cleaner,cleaning temperature,cleaning time and other parameters on optics have been carried out.An effective ultrasonic cleaning technology without damage to the surface of optics is achieved.It is found that the standing time of the optics will affect the cleanliness;the freshly polished optics has better cleanliness and shorter cleaning time.更多还原
