Water?
We (human beings/opticians), are used to using the general term "air to glass surfaces" as a way of saying;
"light passing through a refractive medium into free space".
On Earth in our case, free space contains air........... On the moon there is no air.... but light passing through refractive mediums into a vacuum is still same......only that the light rays are not degraded by air's refractive properties.....
(On Earth we call it focus breathing JoJu..........on the moon it's called focus (last) gasping)... :o
