Infra Red technical details

I wish to take IR images of faint graphite inscriptions on C19th prints. So I am considering converting one of my Olympus cameras (P5 or M5ii) to full spectrum by removing the IR cover filter (using a commercial service). Advice would be welcome. The OM help service was not able to provide anything.

Specifically:

Is the IR wavelength/ sensitivity of the sensors known? Is the IR wavelength/transmission of the 60 and 30 mm macro lenses known? Will the auto focus work with IR?
i.e. would it work? If so, which body would have better properties?

As an aside, are these details known for UV wavelengths, to which the conversion would also provide access?

Thank you
