这是一整句。关于激光机镜头的保养。
Any work on the beam delivery systems (mirror replacement, cleaning of bellows) can potentially leave contamination on the convex surface of the lens. Ensure that beam delivery system is sufficiently clean before installing ULA lenses.
It’s sometimes cost effective to manage this risk with slightly used but good older lenses (or high quality reconditioned lenses) to get through this uncertain period.

这个我已经翻译好了：光路传输系统（镜头更换，清洗波纹管）任何动作都可能在镜头的凸面留下污染。确保在安装超镜头之前光路传输系统是完全清洁的。

这句我真不能理解。脑袋都想破了

这句没什么难理解的。
为了控制这种风险（指镜更换，清洗波纹管等工作），有时候可以用轻微使用过的，良好的老镜头（或高品质的翻新镜片）来完成这种不确定的阶段，这样更加划算。
