The cutview is very interesting. My hat's off to Swarovski for providing such revealing and detailed information. Even with all this, however, some things are not completely clear.
Starting with the objective, the "paper thin" element is clearly a neutral flat designed to protect the first objective element, which for reasons I don't understand, appears to have been placed outside the rubber o-ring seal. It's not completely clear whether the next two elements are cemented or have a narrow air space.
The focusing element appears to be a conventional singlet.
The field flattener doublet comes before the objective focal plane, making it optically part of the objective, which all adds up to six elements, not including the flat. It's not completely clear whether the flattener is cemented or air-spaced, but I suspect air spaced. The front element looks like it could be cemented to the back of the prism cluster.
The eyepiece looks basically like a 4 element Koenig; singlet field and eye lenses with a cemented doublet in between. This is different from the current 4-element EL eyepiece which is a 2-1-1 arrangement.
Altogether a very interesting and very complex design; a big departure from the current EL, not just a refinement. There are certainly at least 18 glass to air surfaces, but more likely 20 or 22, possibly even 24. The current EL has 14. Hard to see how light transmission can reach 90% in such a design, even with improved coatings. Most odd to me is the placement of the first objective element. Why was it placed outside the o-ring?
