A Step Towards Infinity

Ever since their introduction by Horatio S.
Greenough, stereo microscopes have worked
according to the optical principles based
primarily on Ernst Abbe's research. For over a
century, ingenious optics designers and engi-
neers have worked to push magnification, reso-
lution and image fidelity to the limit permitted
by optics.
In doing so, they have always been constrained
by the interrelation between three factors: the
higher a microscope's resolution, the lower the
available working distance. If one increases the
distance of the optical axes, the three-dimen-
sional image seen by the observer becomes
distorted – a sphere becomes an ellipse, a flat
surface curves towards the observer.

Limits are made to be broken.
The Leica M205 FA is the world's first fluores-
cence stereo microscope with a zoom range
of 20.5:1. This accomplishment, however,
was not enough for Leica's engineers. With
the new FusionOptic in the Leica M205 FA /
M205 FCA, they have succeeded in going yet
another step beyond previous limits. In addition
to the increase in magnification, the resolution,
too, has been increased to up to 1,050 lp / mm,
which corresponds to a resolved structure size
of 472 nm.
Of course, this increase in performance benefits
your everyday work. Set up your specimens
on the microscope table with comfortable
freedom of movement and discover details in
stereo microscopy that you could never see
before.
