AFIK the glass on the Bayer filter is borosilicate rather than spectrosil.

Quite probably not either, there are hundreds of types of glass, I think we can be pretty confident it won't be quartz (spectrosil or any other brand). The filtering dyes will absorb some UV, but removing the bayer layer is making for a very specialist camera so most will be happy to live with it's effect.

It means switching to very old technology but I guess I should give my SD14 a go. With the dust protector.hot mirror removed (single screw DIY job) it's a converted camera with no bayer filter. The foveon design also means most IR is seen in the red channel & UV should be mainly in the blue so getting rid of IR leaks from cheap filters is just a case of selecting the blue channel
