Abstract : A new method of protecting UV-transparent films from damage under conditions imitating the climate in the moist tropics is described. The method calls for treatment of two- and three-layer coated quartz parts in chemically pure lauryl alcohol at temperatures over 200C, which gives the coating films reliable stability against the effects of moist air at high temperatures, without influencing the transparency of the films in a broad range of the UV portion of the spectrum.
