Am I correct in thinking that you (both) have (only) calculated what the thickness of the shielding foil would have to be to be adequate for a CPC?
Does this bear any resemblance to what the thickness actually is or are you assuming the manufacturer will have made it adequate for a CPC when that isn't really its purpose?
