加拿大-法国-夏威夷望远镜公司正在进行一项长期实验，以确定最有效的方法来维护3.6米主镜和1.6米次镜裸露的铝涂层。该实验旨在揭示反射率随时间和维护程序而降低的速率。本文报告的结果使我们能够安排预防性维护计划，大大延长暴露在莫纳克亚山顶环境的镜子上的铝涂层的寿命。
The Canada-France-Hawaii Telescope Corporation is conducting a long term experiment to determine the most efficient procedure to maintain the exposed bare aluminum coatings of the 3.6 meter primary and the 1.6 meter secondary mirrors. The experiment is designed to reveal the rates at which reflectance degrades as a function of time and maintenance procedure. The results reported in this paper have allowed us to schedule a preventative maintenance program that significantly extends the life of the aluminum coating on mirrors exposed to the Mauna Kea summit environment.
