Hi all, I'm enjoying my "new" Leitz Dialuz POL, circa 1960. I bought some thin sections from a gentleman in the UK, very nice quality. This is a volcanic rock from Germany with lots of glass (dark in polarized light) and some nice Olivine crystals. Cheers!

Olivine crystal under POL
Re: Olivine crystal under POL
Nice job and very cool to see the crystal "pop" under the lighting. I'll bet it was even prettier through the eyepieces
