    • Glass surfaces are modified using controlled chemical corrosion to reduce reflection for a variety of existing optical and ophthalmic silicate glass compositions containing at least 5 weight % of alkali metal, using neutral or slightly alkaline aqueous solutions (pH: 7.0-8.5) at temperatures of 20.degree.-100.degree. C. The solutions contain an electrolyte having a dissociation constant greater than 10.sup.-6 and contain a polyvalent metal ion. Selection of the proper range of the ratio of glass surface area treated to treating solution volume is critical for achieving satisfactory results for optical applications as well as for making the process simple, repeatable, and inexpensive.Using this invention, antireflective surfaces may be produced on optical devices of complex configuration with high uniformity. Such surfaces provide substantially improved performance in high energy laser systems where exposure to laser light of extremely high intensity and short duration will destroy or degrade conventionally applied coatings.
    • 使用受控的化学腐蚀来改变玻璃表面,以减少含有至少5重量%碱金属的各种现有光学和眼用硅酸盐玻璃组合物的反射,使用中性或微碱性水溶液(pH:7.0-8.5),温度为20℃ DEG-100℃。溶液含有解离常数大于10 -6并含有多价金属离子的电解质。 对处理溶液体积的玻璃表面积的比例的适当范围的选择对于在光学应用中获得令人满意的结果以及使该方法简单,可重复和便宜是关键的。 使用本发明,可以在具有高均匀性的复杂构造的光学器件上制造抗反射表面。 这种表面在高能量激光系统中提供显着改进的性能,其中暴露于具有极高强度和短持续时间的激光将破坏或降解常规涂覆的涂层。
