Laser mirror cleaning: a disruptive technology

Abstract

During the 2022 Astronomical Telescopes and Instrumentation SPIE, Sener presented a novel concept of a system for cleaning of optical surfaces, initially conceived for ground-based astronomical observatories. The proposed concept is based on laser cleaning, a technology broadly used in industrial application, which has been carefully adjusted to gently cleaning the mirror while guarantee the integrity of the coating and, even more important, the substrate. This paper reports the obtained results during the system tests and presents the conclusions and summarizes the following steps in the product development.
