4.12.4 Hints on the use of the HRZ 200 fine focusing stage
4.12.4.1 General description
The HRZ 200 fine focusing stage is a compact attachment for the Axioplan 2
MOT
and Axiovert 100 M
microscope stages, which allows the particularly fast and high-precision fine focusing of the object. The
HRZ 200 permits fine focusing over a range of 200 µm, with the smallest step width being less than
10 nm, reproducibility better than 40 nm, and the maximum speed amountig to 10 Hz. The stage allows
the use of specimens with a weight of less than 100 g.
The HRZ 200 is not used if manual coarse focusing is performed. To position the objective in relation to
the optical z-axis, the standard xy-microscope stage is used.
The HRZ 200 features a mount for standard object carriers of 76 mm x 26 mm x 1 mm and a milled-out
receptacle for 36 mm x 1 mm Petri dishes.
4.12.4.2 Application fields
High-precision fine focusing and translation of the object along the optical axis.
Fast and high-precision mounting of one-dimensional
z
-line sections.
Fast and high-precision mounting of two-dimensional
r-z
-longitudinal sections.
Fast and high-precision mounting of
xy-z-
stacks for the three-dimensional reconstruction of
the object.
Exact measurement of Point-Spread-Functions for deconvolution.
The HRZ 200 can only be used in the Expert Mode.
