    Real calcium fluorite in NL binoculars?

    Thanks Henry for the info. You are correct and I checked it again with the laser. The rear element in the Zeiss shows a faint line but not completely invisible like in fluorite.

    Real calcium fluorite in NL binoculars?

    My Zeiss SF looks like it has a true Flourite element in the rear objective glass. Front glass has a dot with line and another dot and than no line and just a dot.

    Real calcium fluorite in NL binoculars?

    B&H says that the NL has fluorite containing HD lenses. On the EL it just says Flouride glass. Just wondering if it’s real fluorite like the Takahashi telescopes.
