Hi,

A general question for anyone out there who is familiar with Nikon microscopes (including any Nikon representatives that may be listening in on the listserver):

Is the mechanical tube length (also called the "reference focal length" on infinity corrected systems) - ie: the distance between the objective and the microscope tube lens the same on a Nikon FN1 upright microscope as it is for a single-deck Nikon Ti Eclipse inverted microscope?

For reference:

Many thanks if anyone out there knows the answer.

Cheers,

John Oreopoulos

Nikon, Leica, and Mitutoyo use 200mm.
