At AggieFab at Texas A&M, we have windows along one side of the mobile cleanroom (MCR) units that face a hallway that has windows to the outside. The natural light is quite pleasant. We applied yellow film along the MCR windows for the bay where litho processing
is done. We have not experienced any issues.</div>

Hello, in the planning of our new facility the architects have placed windows along a side of the cleanroom (which is fine). Outside of the windows is a hallway which is lined with large windows to the outside. This would allow for sunlight to pass through
two sets of windows and into the cleanroom. <span style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt">Although standard windows are adequate for filtering a majority of shorter wavelength UV, some of the longer wavelength UV (UV-A, ~300-400
nm) will still transmit. It is of my belief that it's standard practice not to have sunlight entering the cleanroom (especially a litho area). </span></div>

Are any of your cleanrooms exposed to sunlight (I haven't seen any) and, if so, what type of window filtering do you use?</div>
