--------------------------------------------------------------------------------
Anti-reflecting coatings are used to increase the transparency of optical systems by the decrease of reflection losses at surfaces of optical components. Under such effect intensity and contrast of an image increase that is achieved as the result of the reduce of light scattering which forms flashes and other defects of images. The most considerable rise of light flow due to the presence of anti-reflection coatings takes place in multi-component systems and systems that contain high-refracting components.
