The functions of a microscope can be analyzed into the mechanical and optical
systems.
To those who are engaged in line of microscope repair, it is a self-
evident truth that if the optical system is not correctly adjusted, the fundamental
function of the microscope may be lost.
Among the various types of microscopes, the stereo microscopes such as the OLYMPUS
Stereo Microscopes Models X and X-Tr require most difficult and complicated tech-
niques to repair.
Prior to repair of them, read this manual and make yourself
familiar with these models so that you can find what parts are defective and
degrees of their damages.
In case of the Models X and X-Tr it is necessary, first of all, to find out what
lens(es) or/and prism(s) is(are) the cause(s) of the microscope mulfunction.
Checks and repairs of these models should be carried out in the following orders:
1.
Porro prisms
2,
Parfocality of drum lenses
3.
Total deviation of drum lenses
4.
Optical axes of left and right fields of view
Each of these 4 items can be checked and repaired individually.
However, if you
observe a double image through the binocular observation tube, for instance, the
optical axes of the left and right fields of view are not coincided, simultaneous-
ly and totally due to the items 1, 3, and 4 mentioned above,
These 3 steps must be
repaired in the order 1-3-4,
You cannot change this order, because if you complete steps 3 and 4 prior to step 1,
you must repeat checks and repairs steps 3 and 4 after completing step 1.
If you get skilled in repair of the Model X and X-Tr, the optical adjustments of
the other OLYMPUS Stereo Microscopes except the Model SZ-III become more easier
because they are of the same optical system.
