Hi Christina and Matt,

I spoke briefly to Tim regarding the mechanical strength needed of the 
acrylic pane and he thought that 0.5 inch thick was a reasonable 
starting point. It could be thicker of course. I don't see a need to try 
thinner sheets as we want them to have fair mechanical strength.

Cheers, Elton.

>> Attached to this message is a quick sketch that John Frye made that is a rough conceptual design for how to mount the acrylic pane in front of the FCAL.  I think this conveys the general idea.  What we don't know is how you plan to integrate your LED pulsing system into this.  Where should boards go?  Should we revise to the design slightly so it could be detached as a single unit (for example, if we want to do UV curing of the glass)?  At our last meeting there seemed to be some confusion about the general concept and geometry, so this is maybe a good place to start.
