Paper Abstract

Exfoliation of optical thin films at high humidity in the air is serious problem. Deterioration of three kind of optical thin films deposited on three types of substrate with different water-resistance at high humidity condition was studied. Thin films deposited on fused silica glass with highest water-resistance showed a best result for the exfoliation problem. Silica film seamed to be best for the surface observation at high humidity, but the laser -induced damage threshold was considerably lowered.
