| 58.10 | Anti-reflection coating question | LANDO::NIEMI | | Thu Mar 20 1997 12:56 | 8 |
| Question on the wave theory behind an anti-reflection coating: I can
see how the thickness of the coating can be adjusted so the wave
reflected from the interface between the coating and glass is out of
phase with the wave reflected by the air-coating interface and
therefore in effect cancels it. But how does a anti-reflective coating
increase the transmission of the glass when it would appear more of the
light's energy is lost with the portion reflected back from the
coating/glass interface? Any ideas.

Does it increase the transmission? An optical system will give a more
"contrasty" image if there are fewer reflections, but I'm not sure there's an
increase in transmission.

| Energy is not being destroyed when out-of-phase wave function
values are added and cancel each other. The cancellation
lowers the probability of finding the photon at particular
points in space-time (for example, the back-at-you side of the
glass+coating) thus increasing the probability of the photon
being found elsewhere (for example, the other side of the
glass).
