[time-nuts] LPRO questions...

[Alan Kamrowski II]

Hi Magnus,

Interesting.  What temperature C do you use and for how long?

Thanks,

Alan

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.

Cheers,
Magnus
