considered: 100x, 400x, then 900x. Each time the magni-
fication changes (due to the objective change), the image
sharpness must be readjusted with the focus knob. When
doing this, be careful because if you move the microscope
stage too quickly, the objective and the slide could come
into contact and cause damage to the slide or microscope.
For transparent objects (e.g. sea salt), light is projected
by the lower light traveling from below the stage, through
the objective and eyepiece, and finally into your eye. This
process of light transmission is known as microscopy.
Many micro-organisms found in water, plant components,
and the smallest animal parts are transparent in nature.
Opaque specimens, on the other hand, will need to be
prepared for viewing. Opaque specimens can be made
transparent by a process of treatment and penetration with
the correct materials (media), or by slicing. You can read
more about creating specimens in the following Microscope
Experiments booklet.

Cleaning Tips
To ensure your microscope has a long service life, clean the
lens (objective and eyepiece) with only a soft, lint-free cloth,
like a microfiber cloth. Do not press down too hard while
cleaning, as this might scratch the lens. Ask your parents
to help if your microscope is really dirty. The cleaning cloth
should be moistened with cleaning fluid and the lens wiped
clean using very little pressure. Make sure your microscope
is always protected against dust and dirt. After use, leave
it in a warm room to dry off.
