The back end as mounted is where you want it to deposit. When I did it,
it turned out that I better put the "window" side downwards so that when
the vapor rose as it was hot, it hit the cooler side above it and
settled there, that's how I reduced the shadowing on the window to
clear. The reason it's a bad thing is that this thin coating will absorb
exactly that wavelength you try to output.
