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>
