ABSTRACT:
A color selective, anti-reflective optical coating has a substrate (42), a first layer (44) and a second layer (46). The first layer (44) has an index of refraction that is 25% to 39% greater than an index of refraction of the substrate (42). The first layer (44) has a width of between 12.31 nanometers and 13.41 nanometers. The second layer (46) has an index of refraction that is between 1% and 17.5% less than the index of refraction of the substrate (42). The second layer (46) has a width between 118.32 nanometers and 130.78 nanometers. When the color selective, anti-reflective optical coating is applied to a head lamp lens (40), it significantly increases the output of the head lamp (20) and has a distinctive tint.
