“The principle of coatings is to reduce the light reflecting on the glass surface. If the coating has a ¼ wavelength thickness and the glass an index of refraction higher than the coating the 2 reflections are in phase opposition and cancel. For 1 multicoated surface, the transmission can increase up to 3.5%”
