Despite all of our efforts to align the beam through the window, the beam coming out of the window was diffuse, indicating that the window is likely contaminated. If this is true, then further work on attempting to align the beam is useless until the window is properly cleaned. We did wipe the window on the shower head side several times, but no improvment was observed.
