Abstract

The windows of modern automobiles are growing larger and larger. The larger the window, the greater its angle of inclination. This causes some problems for the passengers and their compartment. One well-known problem is the heat irradiation into the car. For a long time green tinted glass has been used to solve this problem. Some coatings have been developed to solve this heat problem. But with greater angles of window inclination a new problem appears: the visible light transmittance decreases. At an angle of 70° the transmittance through the windshield is only 50% from the driver's viewpoint. The only way to solve this problem is by special antireflection coating. First tests with such coatings have shown that it is possible to achieve both the right optical function and the necessary hardness.
