General Microscope Care
Unpacking
Your stereo microscope is shipped in a two-
part Styrofoam case. Keep this case for
storage, transport, and shipping. It is perfect
packing material should you ever need to send
your microscope in for repairs covered by the
warranty.
Fit the rubber eye guards onto each
eyepiece. The widest portion should be on the
outside of each eye.
Avoid touching the lens surfaces on the
eyepiece or objective lens, as finger prints will
decrease image quality.
Cleaning
The best optical quality can be
compromised by dirty lenses. Using a dustcover
and cleaning the lenses regularly will greatly
enhance your microscope use.
To clean lens surfaces, remove dust by
using a soft brush or a can of compressed air.
Then moisten a piece of lens paper (our item MI-
PAPER) with some lens cleaning solution (MI-
LENSCLN). Gently clean the eyepiece and
objective lens exterior surface using a circular
motion. Repeat with a second paper moistened
with solution if necessary. Repeat once again
with a piece of dry lens paper until the lens is
clean and dry. Do not spray lens cleaner
directly on the lens.

Description of Components
1. Eye shields: These rubber shields fit over
the eyepieces to block light and provide
comfort.
2. Binocular head: This is the part of the
microscope that you look through. The
binocular eyepieces contain lenses that
magnify 10x and provide an unreversed 3D
stereo image. They are inclined at an angle
for comfortable viewing.
3. Diopter: This knurled band on the left
eyepiece is used to adjust the focus for
differences between your eyes. Instructions
for doing this are on page 4.
