Lensmaking companies advertise their Anti Reflective coatings as providing greater contrast due to the transmission of more light. Does this mean that the light that would normally be reflected now pass through the lens? If an Anti Reflective coating is applied to a lens is there a detectable increase of transmitted light? It bothers me that there are two inconsistencies with the law of conservation of energy with A.R. coatings. Where does the energy go from destrucitive interference (the reflected ray) and where does the extra energy come from for the stronger refracted ray?
