Problem innotec SNF 2008-05-19 15:10:44: Users are advancing the Film in front of polarized window too much

[jperez at snf.stanford.edu]

New roll of film has been replaced on Innotec. The film is a 
clear teflon color, may be brighter to your eyes. If so, you'll have
to dim with the rotation of the polarized knob.
Jim found a 20 foot length of film with NO deposition. Please
 only advance the  film no more than a quarter turn! The strip
 of  film that has NO dep. is attached on the side of Innotec
