Yes. I do not use the "c" (clone) term because even lenses with seemingly
identical block diagrams can differ widely...
The 50/1.5 Xenon for Leica, according to Greenleaf, shows two rear elements...

These are shown in some of the Kodak lens booklets
included in the _Kodak Reference Handbook_ but also sold
separately. Both the Xenon and the Zeiss Biotar were
designed after the Opic but are not copies of it. They
simply follow the same general layout.
There are a number of lenses with the Xenon name. All are
Opic or Biotar types but some have more elements. Schneider
made a Xenon for Leica and made a variety of Xenon motion
picture lenses, once standard on Arriflex cameras.
