PROCESS OF DEPOSITION OF OPTICAL COATS

摘要

FIELD: manufacture of periodic elements of raster on articles. SUBSTANCE: vacuum-magnetron sputtering of material on to backing through mask with periodic structure having profile varying by thickness is conducted in argon and oxygen atmosphere. Profile specifies relief of deposited transparent optical coat with variable radius of curvature that changes by law of stochastically oscillating or periodic function with preset refractive index. As result transparent backing with deposited periodic optical elements of raster is used in the capacity of three-dimensional films for black-and-white and color screens of television receivers, displays and glasses with patterns. EFFECT: invention makes it feasible to widen technological capabilities of ion-plasma method for manufacture of optical elements of raster with preset refractive index on objects made from any transparent material with less labor input during one cycle of treatment of article. 5 cl, 4 dwg
