How do you cut light diffuser?

I am replacing the flat sheet lens that covers the fluorescent light tubes in my kitchen. First off, are these things properly called "diffusers" or "lenses" or what is the term I'm looking for? It is the sheets of thin plastic textured material that covers recessed light fixtures, like in a drop ceiling.

Secondly, how do you cut that stuff?

Thanks,

I use a plexiglas cutter and straight edge. I have also on occasion used my table saw set at 1/16th inch in height, then flip it over and re run it. Otherwise the saw would shatter it like glass.

Can you send me a link to the proper tool? I do not own a table saw. Is it like a scoring tool of some sort?

Here's a link for graphic purposes. I just googled it and here's what came up. You can buy them locally, however. http://www.aircraftspruce.com/catalog/mepages/plexicuttool.php

Are those things tricky to use? Will I end up breaking my lens and end up with little pieces of scrap?

Thanks

I use a table saw set low and run the lense backwards through the saw, or

a razor knife, just scoring the plastic and running the knife over the cut line about 20 times for each cut.

If your lens is beaded on one side, you can only cut it with the scoring tool from the smooth side, and if you score it enough, it will break along the score. The easy way to make sure you crack it straight after scoring it is to lay the entire length over a 1/4" dowel and press equally on both sides.
