Damage and removal of the coating on the first lens of the MegaCam wide-field corrector

Autor: Derrick Salmon, Tom Benedict, Gregory Barrick

Publikováno v: SPIE Proceedings.

The coating on the exposed surface of the 810 mm diameter first element of the MegaCam wide-field corrector at the Canada-France-Hawaii Telescope (CFHT) was found to be degraded in the fall of 2014. An investigation showed that the coating was, in fa
