Hi all, Sorry it took me so long to respond to the original question. The IR blocking plastic I got was from Edmund Scientific's Industrial Optics division, part number K43-949 (for a 2" diameter disc). It is available in various sizes but is expensize, $7.00 for the 2" disc. It also didn't do the trick in my case, apparently because there is so much IR in daylight anyway.
