The Nikon UV-F 100x NA 1.3 arrived (along with a 10x Fluor NA 0.5 as well) so I measured the transmission of them in the UV.
The Nikon UV-F 100x NA 1.3 is as follows (note that transmission is normalized 0-1 as the diameter of the rear element of this is smaller than the light beam in my measurement setup). It transmits down to about 310-320nm which is in keeping with what the paper you shared mentioned.
The Fluor 10x NA 0.5 also had good UV reach. Unlike the 100x UV-F, this is now absolute transmission as the rear element on it is huge. As the with UV-F this would be good down to about 320nm.
Both of these would offer great transmission for 365nm work (as for image quality at that wavelength that remains to be seen).
For those who haven't seen one, here's a photo of the Nikon 10x Fluor. Some big chunks of glass in there.
