Olympus POS Instruction Manual
CAUTION
1. Generally speaking, the POS should not be used where the temperature is higher than 50°c.
Sudden changes in temperature or humidity produce moisture on the lenses and other parts
of the microscope. This not only obscures vision but also causes corrosion.
2. The POS must be carried about with care since the slightest shock can impair the fine adjust-
ment system.
3. The POS should be kept free of dust since dust, together with moisture, can cause molding.
Dust on the optical system, especially the polarizer and analyzer, causes double refraction,
which in turn dims contrast. The POS, therefore, should be covered with the vinyl dust
cover immediately after use. If it is not used for some time, it should be kept in the case.
4. High temperature adversely affects the polarized plate of the polarizer and analyzer.
Therefore, it should not be exposed over a long period to strong sunlight or illumination
(more than 60°c).
5. Since the POS is a precision instrument, it should not be taken apart without adequate reason.
