I have acrylic whose edges are not clear i.e they are white in color due to cutting.So does ftir table need a clear edge acrylic to
fit leds? or is it fine if edges are milky

They don’t have to be polished but it’s good to have it sanded down a little. Mine was cut with a -1 rake and you can see into the acrylic. I might touch it up with some fine sand paper but not going to polish it.
