Care of the Microscope 39
General Maintenance (Continued)
O
No part of the microscope is quite so
vulnerable to collecting dirt, dust, and oil
as the front lens of the objective. When-
ever you encounter lack of contrast, cloudi-
ness or poor definition, carefully check the
condition of the front lens with a magnifier.
O
Cleaning 40× and 100× objectives requires
more care. Note: To achieve the high degree
of flatness obtained with higher magnifica-
tion objectives, the objective has a small
concave front lens of fairly short radius or
curvature. The surface of this front lens can
be readily cleaned with a toothpick covered
with a cotton tip, or with a small cotton
swab. Moisten the cotton with commer-
cially available glass cleaner. Wipe the
front lens lightly without applying undue
force or scrubbing action. Make sure that
the cotton tip contacts the concave lens
surface. Check the objective with a magni-
fier after cleaning.
O
If you need to remove the microscope’s
viewing body, be careful not to accidentally
touch the outer lens surface (located on
the underside of the body). Fingerprints on
this surface will reduce image clarity. This
lens can be cleaned in the same manner as
objectives and eyepieces.
Illumination
O
The Leica DM500 uses LED illumination.
Therefore, no lamp changing is required for
the life of the microscope.
