lens (U-TLO) depending on your observation requirement.

# When replacing the top lens, make sure not to apply ex-

cessive force to the top lens arm.

tacts lightly with the lens holder.

Notes on Oil Immersion Top Lens

# Before engaging or disengaging the top lens, lower the

condenser holder and wipe away oil deposed on the top

lens.

(If you attempt to engage or disengage the top lens with-

out lowering the condenser holder, the slide glass may

impede the operation.)

# If a slide glass thicker than 1.2 mm is used, the field iris

diaphragm image may remain fuzzy.

# Use the oil immersion top lens in combination with an

objective of 20X or higher magnification.
