重新镀膜是常规操作。
间隔时间,那就受很多因素影响了。
看一下大名鼎鼎的Zambuto关于镀膜的说明:
Update January 20, 2022
Folks, we're resuming coating services on a limited basis for Zambuto mirrors (and related secondaries) only. We're unable to provide coating service for any other optics, we don't have the time, and that will be the policy going forward. We plan to handle 1-2 per week as necessary. We have a short backlog of customers that I've yet to contact, but we will get to that. Any owners of Zambuto mirrors that need service are welcome to contact us.
