Tv Microscopy - Leica DM R Serie Mode D'emploi

Examp le
The upper and lower surfaces of a thin polished
specimen have been focused with a dry
objective (n = 1.0) scale readings of the mechanical
i
fine drive (division spacing = 2 m) : 19.0 and 12.5.
Therefore d' = 2 x 6.5 µm.
The refractive index of the object detail was
taken to be n = 1.5.
o
Thickness d = 2 x 6.5 x 1.5 = 9.5 µm
