FIELD: physics.
SUBSTANCE: method of making tinted film includes joining polymer sheets made of transparent material, a coloured optically transparent elastic polymer deposited on one of said sheets in form of dots, polymerising and joining with another sheet by superimposing and sealing on the periphery. A coloured optically transparent working fluid is fed into the space between the films through a valve to control the degree of light transmission by feeding and removing said fluid. The working fluid is selected under the condition that for the same thickness of the layer of the working fluid and the coloured optically transparent elastic polymer, their hue, light transmission and refraction index match or are very close.
EFFECT: controlling the degree of light transmission and improved optical characteristics of surfaces depending on operating conditions.
