Hello all,

Looking at my copy of the Leitz manual "Image-forming and Illuminating
Systems of the Microscope" it states on page 49: Phaco phase contrast
objective for the Zernike condenser are 170/0.17/45mm (with the
exception of the Fl Oel 70 - 170/0.17/37mm)

Page 50 lists the Phaco NPL Phase Contrast Planachromats for the Zernike
condenser at 170/0.17/45mm, but page 51 lists PV Phase contrast
objectives for the Heine condenser at 170/0.17/37mm (with three
exceptions for 170/0.17/38.5mm!)

I have sets of the achromat phacos as well as the NPL Phacos, all or
which are 45mm (none for sale, I'm afraid!)

Hope this helps.

All the best,
Mike
