Abstract : In gigantic telescopes the diameters of main mirrors reach several meters, and these mirrors weigh many tons. This, of course, makes the assembly and exploitation of the installation, difficult. A substantial deficiency is that the reflection coefficient of ordinary glass mirrors is only about 0.71. Scientists of Uzbekistan decided to produce mirrors which are more convenient in use and more economical. Right now this problem has been solved successfully. The scientists tested a metal plated synthetic film which reflects up to nineteen percent of luminous energy. The use of such pellicular mirrors offers the possibility of considerably reducing the weight of installations which collect solar energy. (Author)
