Paper Abstract

Many optical surfaces such as space and telescope mirrors are historically "uncleanable" and extraordinary measures are utilized to remove, recoat and therefore subsequently realign astronomical telescope systems resulting in extensive downtimes. Others, such as those used in space systems are extremely sensitive to organic contamination and particulate and residue removal is critical to performance. In this paper we present some recent data and examples that the strip coating First Contact Polymer, resulting from R&D from our labs, restores astronomical mirrors to like new condition by cleaning in situ and provides superior cleaning & protection from recontamination for telescopes, space instruments and other technologically important surfaces. We will also present data that these polymeric systems clean to the atomic level and that Laser Induced Damage (LIDT) results indicate that it leaves no residue. We will present details and supporting evidence that that our polymers, that were a critical enabling technology in LIGO’s Gravity wave discoveries of 2016, can greatly extend the lifetime of current mirror coatings on large astronomical mirrors.
