Note
：
When using the 40X objective, you won
’t need to apply oil drop on the oil condenser.
When using the 100X objective, the condenser won
’t work well if no oil drop applied
on the condenser.
When you apply the immersion oil with the 100X objective, do not let the immersion
oil to contact with the dry objective lenses (especially the 40X). If the immersion oil
is on the dry objectives lens, please use the lens cleaning paper to clean the
objectives lens in time. The oil will damage the dry objective lenses.
After observing the specimen with the 100X objective, clean the 100X objective lens
first.
