CAUTIONS:
1.
A sudden change in humidity and temperature causes moisture on
the surface of the lens, resulting into the hazy effect during an
observation.
It
further brings about mildews and corrosion'.
In
general, a high temperature is not preferrable.
2.
Avoid giving a severe impact to the instrument.
The very fine adjust.
ment may be ruined.
Be sure to carry the instrument carefully.
3.
After its use, wipe off ceder oil at the tip of the objective with a
piece of gauze soaked with xylene;
if anisole is used, simply clean
it with a piece of dry gauze.
Any trace of oil left on the surface
of the lens will cause an adverse effect on it.
4.
Dust, along with humidity, will also cause an adverse effect and
mildews on the lens.
The instrument is dust-proof but an utmost
precaution will never do a harm.
Especially, dust accumulated in
the optical path from the polarizer to the analyzer, will cause the
bi.refringence resulting inlo a low contrast.
After the use, therefore
be sure to cover it with the alastic cover provided.
If it is not to
be used for a long time, return it to the cabinet.
5.
The polarizing filters used for the polarizer and the analyzer will
become inferior in its efficiency if exposed to the temperature over
60°(.
It is risky to expose it to sunshine or to the strong illumina-.
tion for a prolonged time.
6.
A microscope is a very finely adjusted instrument.
Refrain from
disassembling the mechanical parts.
Particularly the optical system
requires a rigid and
minute
adjustment and,
therefore, must
absolutely be left to the specialist.
In case of any neeessity for
repair, please contact our company or our agents.
