Sonot really usable. Are you testing wide open here? The noise or internal reflections are quite strong.

Yes, it's wide open. Reflections are from spectroscope inside surfaces. Had to point sun to have something visible in UV part without sensor noise.
Lens is very well corrected and sharp in full spectrum range even wide open.

I think T0.95 does mean something close to f0.85
