    Abstract: In a method for connecting two elements (1, 2) at least one of which consists of fused silica, wherein both elements (1, 2) are connected to each other through fusion bonding in a gas atmosphere (5), preferably at temperatures between 300° C and 1000° C, the hydrogen portion in the gas atmosphere (5) is adjusted such that reduction of the hydrogen content of the fused silica first and/or second element(s) (1, 2) is substantially prevented. An optical component, in particular, a terminating element (6) for a projection objective of a microlithography projection exposure apparatus is produced in accordance with the method.

    Abstract translation: 在用于连接两个元件(1,2)的方法中,其中至少一个由熔融石英组成,其中两个元件(1,2)通过在气体气氛(5)中的熔接相互连接,优选地在 在300℃和1000℃下,调节气体气氛(5)中的氢气部分,使得基本上防止熔融二氧化硅第一和/或第二元素(1,2)的氢含量降低。 根据该方法制造光学部件,特别是用于微光刻投影曝光装置的投影物镜的端接元件(6)。
