<p class="MsoNormal" style="background:white"><span style="font-size:12.0pt;color:black">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. 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). <o:p></o:p></span></p>
