Not that I'm aware - but then I don't have such an instrument. Physically the i1 doesn't seem that different to the Spectrolino, which does have an interchangeable filter system. It's easy enough to remove the i1's cover glass, so if the UV filter is implemented the same way as the Spectrolino, in theory all you have to do is replace it with the non-UV version. But: Maybe it doesn't have the filter in the same spot and the i1 doesn't have separate calibration data for UV vs. non-UV. The latter could affect accuracy. Graeme Gill.
