1 Notes

Operation!

The instrument may be operated by
trained personnel only who must be
familiar with the possible dangers in­volved in microscopy and the relevant
field of application.

Dust!

Dust and dirt can impair the perform­ance o f the instrum ent. Theref ore, pro­tect the instrument against these inter­ferences as far as possible. Always use
the dust cover if you do not intend to
use the microscope for longer periods
of time.

Use of toxic immersion agents!

If the toxic -bromonaphthalene is
used as an immersion age nt, make sure
to avoid all skin contact with this sub­stance to elimi-nate the possibilty of
health risks. Wear protective goggles
and gloves, if necessary..

Damage to microscope parts!

To eliminate collisions between the
objec-tives and parts of the universal
rotary stage during work, the 4-position
objective nose-piece of the
must be equipped with no more than 2
objectives, with a free nosepiece eye
between each objective. The 6­position nosepiece of the
may accommodate 3 objectives
(always separated by a free eye). Use
caps to close nosepiece eyes not in
use.

3 Application

The three-axis universal rotary stage (FigFig. 1/1) is
mounted on the rotary stage of the polarization
microscope of the

Axiophot Pol

Axiolab Pol,

the

und

microscopes. For

the universal rotary stage is
equipped with a special stage carrier (Fig. 1/13)
and mounted directly on the stand in place of the
rotary stage. Observation and measurement is
generally possible in the orthoscopic and the
conoscopic mode. Linearly polarized and circu­larly polarized light can be used. With the help of
one rotary and two tilting axes (stage 1), the three­axis universal rotary stage is suitable for aligning a
crystal, which normally is birefringent, in any de­fined direction relative to the optical axis of the
microscope.
The major fields of application of the universal
rotary stage can be classified into three catego­ries:

Crystal diagnosis



Determining the optical character



Determining the absolute birefringence



Determining the grinding thickness



Measuring position and dimension of indicatrix



Measuring the optical shaft angle



Measurement of morphological reference planes,
such as cleavage faces, composition surfaces of
twins or the periphery of idiomorphous unit crys­tals



Determining the pleochroism

Determining the chemical composition of mixed
crystals



Examination of plagioclases



Analysis of alkali feldspas



Analysis of pyroxenes and amphiboles

Reinhard [10] and Sarantschina [12] have intro­duced different definitions. The axial designations
of Sarantschina are based on the inventor of the

,

universal rotary stage, E. S. von Fedorow. With the
three-axis universal rotary stage the A
been developed. This, however, is no drawback,
because three axes are absolutely adequate for
aligning any orientation in the sample relative to
the optical axis of the microscope. In addition, the
possibility of operational errors is reduced. Given
the option, old hands will therefore normally give
preference to a three-axis universal rotary stage
over the four-axis one.

Structural analysis

Analysis of the structural arrangement of opti­cally monaxial crystals, e.g. quartz in quartzite
or calcite in marble



Analysis of the structural arrangement of biaxial
crystals, e.g. muscovite in gneiss.

The most customary and also the clearest defini­tion of the axes of a universal rotary stage is the
one introduced by Berek in 1924, in which the axis
numbers increase from the inside toward the out­side. The inside rotary axis, for example, is num­bered A

, the inside tilt axis A2. The rotary axes are
