    obviously the uncalibrated ones are less exact than the calibrated ones. give the uncalibrated ones a 0.10 tolerance on the last step (almost half a stop), very good for usual works, not enough for experimental researchs by densitometer analysis...

    Hello !
    The two are made exactly the same. out of the production line, the calibrated get it's values measured with a "very precise" densitometer and the transmission (or reflection) values written on the packaging.
    This way, you have the exact value of the wedge.
    These are useful if you do not own a densitometer but a way to compare densities values. By using a calibrated wedge you can have a quite precise measurement of you unknown densities using your comparator and the calibrated wedge.

    sad to hear that italy has such slow custom.
    I ordered my newest wedges directly from stouffer and they arrived in envelope (well protected) so there was no customs at all.
